Low-lying electronic states of CuBr
T. Hirao and P.F. Bernath
Abstract: The A1 X1+ and B1+ X1+ transitions of copper monobromide, CuBr,were recorded with a Fourier transform spectrometer. The emission was generated by usinga hollow cathode discharge of Ar buffer gas and a mixture of Cu and CuBr powders. Themass-dependent Dunham expansion formula was used to obtain improved molecular constantsfor the ground, A and B states. These molecular constants provided RKR potential curvesand FranckCondon factors for the AX and BX transitions.

1. Introduction
The spectra of transition metal-containing diatomic molecules have been studied for a long time.Due to the presence of unpaired d-electrons on the transition metal, these molecules tend to have avery dense electronic structure, as well as high spin and orbital angular momenta. The resulting localand global perturbations are often responsible for many misunderstandings in the interpretation of thespectra.
Among the transition metal-containing molecules, the copper monohalides (CuX, X = F, Cl, Br, I)are expected to be relatively simple because they have closed-shell 1+ ground states. Moreover, allof these molecules have been studied by millimetre wave spectroscopy in the 1970s, so very accuratestructural information is available for the ground state [14].
Theexcitedelectronicstatesofthecoppermonohalideswerediscoveredbyvisible/UVspectroscopy.However, it was incorrectly supposed before 1982 that all detected spectra of copper halides were dueto the transitions between X1+ and other singlet states because of the selection rule, S = 0.
In 1982, Ahmed et al. [5] suggested that some low-lying electronic states of CuF were triplet states.Later, Dufour et al. [6] interpreted the spectra with the aid of ab initio calculations. Brown and co-workers [710] and Jakob et al. [11] using laser methods were able to locate the low-lying a3+ and

b3 states. The hyperfine structure was helpful in the characterization of these excited states. Theassignments of the electronic states were consistent with lifetime measurements [1214] and ab initiocalculations [6,15,16]. Moreover, Delaval and co-workers [17,18] set up rovibronic wave functions forCuF from the experimentally observed and ab initio data. The aim was to understand the mixing ofenergy levels through configuration interaction and spinorbit coupling [18]. This extensive work on
CuF has motivated additional studies of the excited states of other members of the copper monohalidefamily such as CuBr.The first spectroscopic studies of CuBr were carried out in the 1920s [19,20], which identified the
A1 X1+ (460510 nm), B1 X1+ (420460 nm), and C1+ X1+ (390460 nm) bandsystems. Later, the D1+ X1+ (370400 nm) system was photographed by Rao and Apparao in1964 [21]. They also detected the CX transition of63Cu81Br and obtained molecular constants for thev = 0, 1 levels [22]. After Rai et al. measured the 01 and 20 bands of the DX system [23], Mansonet al. [4] detected the millimetre-wave spectrum of CuBr for all isotopomers, and obtained Dunhamcoefficients and Dunham potential constants. Based on the quadrupole coupling constants of the 81Brnucleus, they estimated that the ionic-bonding character between Cu and Br was 66%. Later, Mishraet al. [24] recorded the 00, 10, and 01 bands of the AX and BX transitions. They recorded P, Q,
and R branches for the BX transition, but only P- and Q-branches for the AX transition. After therotational analysis, it was found that the sign of the lambda doubling constants, qv , was different forthe A and B states. The positive sign ofqv of the A state was said to be similar to other copper halides[25,26], and the negative sign ofqv in the B state was suggested to be the result of an interaction withthe C state.
After several years,Kowalczyk et al. [27] reported chemiluminescence from thereaction of Cu (2D)with Br2, and discovered the triplet A state, which is located below the A state. They also mentionedthat the A state should be a triplet because of the unusual intensity ratio of the chemiluminescence [27].Recently, Hikmet et al. [28] applied the technique of laser-induced fluorescence to this A state andobtained molecular constants. Considering the analogy between the states of CuF, CuCl, and CuBr,they suggested that A, A, B, and C states should be called a3+, b3, A1, and B1+ states,respectively. We will adopt this suggestion in our paper. Very recently, Sousa et al. [29] performed abinitio calculations with scalar relativistic effects and a fully relativistic four component SCF-CI (Self-Consistent Field Configuration Interaction ) with the DiracCoulomb Hamiltonian. They suggestedthe same labels for the low-lying excited states as Hikmet et al. [28], and predicted the presence of 1and 3 states. They also calculated transition dipole moments for the AX and BX systems, and thecomposition of the wave function for the B1+ state, which consisted of 76% of pure B state and12% of the pure X1+ state, and some less important configurations [29].
In this study, the AX and BX bands in the 450 nm region were recorded by Fourier transformspectroscopy. Applying a comprehensive fit including the previous pure rotational transitions in theground state [3], conventional band constants and Dunham coefficients for the ground and A and Bstates were obtained. Based on the molecular constants, RydbergKleinRees (RKR) potential curvesand FranckCondon factors were calculated. Considering the interactions between the low-lying states,
we estimated the mixing of the wave function of the B state with the ground state.
2. Experimental
An emission spectrum of CuBr was generated using a hollow cathode lamp. The hollow cathode wasmade of copper and had a hole with a diameter of 6 mm. To put more CuBr powder inside the cathode, acopper foil was shaped and inserted into the hole of the cathode. A few grams of a mixture of copper(I)bromide (Aldrich,99%) andcopperpowder (Aldrich, 99%) were placed in the hollow cathode.A currentof 100 mA was applied to generate a discharge with an Ar buffer gas (2 Torr) (1 Torr = 133.32 Pa).Emission from the hollow cathode was focused with a lens into the aperture of the emission port of ourspectrometer.

Fig. 1. Overview spectra of CuBr A1 X1+ and B1+ X1+ systems.
The AX and BX transitions of CuBr were recorded with the Bruker IFS 120HR Fourier transformspectrometer (FTS) at the University of Waterloo [30]. A visible quartz beamsplitter was utilized. Toenhance the sensitivity, a photomultiplier tube (PMT) was set at the back parallel exit. We alsoinserted a 450 nm red pass filter (CORION LG-450-S) at the emission port and a 550 nm blue passfilter (CORION LS-550-S) in front of the PMT. The optical filters were necessary to eliminate the
intense atomic lines outside the observed wave-number region to improve the signal-to-noise ratio. Theemission spectra were recorded in the spectral range from 21 000 to 26 000 cm1 at a spectral resolutionof0.03cm1. In total, 12 scans were co-added. An overview spectrum of the 450 nm region is displayedin Fig. 1. Note that we also succeeded in detecting the weaker b3 X1+ transition, but the spectrawere not as good as the AX and BX bands.
Spectral line positions were measured by using the program PC-DECOMP written by J. Brault.Because all spectra were recorded with the spectrometer vented, the line positions were systematicallyshifted by the refractive index of air [31,32]. To obtain vacuum wave numbers from the observed airwave numbers, we appliedthepolynomial conversion formula describedpreviously [30].After this treat-ment, we calibrated all measured lines on thebasis of theobservedAr atomic line positions.The standardline positions were taken from ref. 33, and the calibration factor was obtained as 1.000 001 5375(71).
3. Analysis
As illustrated in Fig. 1, the spectra show alternate AX and BX vibrational bands from 22 000to 24000 cm1. In the first step, we tried to identify 00 bands, which should not show the isotopicsplitting associated with the different Cu and Br nuclei. Figures 2 and 3 present these bands. The linesare denser near the band origin in Fig. 2 than in Fig. 3 because of the presence of the Q branch inthe A1 X1+ transition. Although the band heads in Figs. 2 and 3 do not show visible isotopicsplittings, all branches were generally split into two series with similar intensities when J increases.Because of this bromine isotopic splitting, we were able to successfully apply combination differencesusing molecular constants in the ground state [4] to assign these 00 bands. For the other vibrational

bands such as 01 and 10, the assignment was straightforward, although the spectra were very dense.
However, we could not find the 11 band in either the AX or BX transitions.To obtain effective molecular constants from the assigned spectra, we applied the conventional band
constant formula and the mass-dependent Dunham expansion formula [34] in a least-squares fittingprocedure, including the previous millimetre wave data [4]. For the 1 state, the energy levels arerepresented by the following expression:

where E is the energy difference between the upper 1 state and the lower 1 state. In the caseof the A state of CuBr, the orbital angular momentum l is equal to 2, assuming that the A1 statehas a Cu+ 3d 1 configuration and the B1+ state is represented by Cu+ 3d1 (see below). TheDunham coefficients listed in Tables 2 and 3 generally obey (5) and (6), indicating that CuBr obeys theBornOppenheimer approximation, as expected for a heavy system.
We also calculated RKR potential curves [36], equilibrium bond length, and FranckCondon factors[37] from our Dunham coefficients. The equilibrium bond lengths in the ground, A and B states werecalculated to be 2.173 453 55(31), 2.223 7210(72), and 2.259 5547(46) , respectively. The calculatedFranckCondon factors for the AX and BX systems are listed in Tables 4 and 5, respectively. Asmentioned above, we did not see any 11 bands, consistent with our calculated FranckCondon factors.
The observed values for qv of63Cu79Br for the A1 state obtained in a band constant fit have onlya small vibrational dependence, 7.6954(108) 105, 7.9477(117) 105, and 8.0580(145) 105 cm1 for v = 0, 1, and 2, respectively. These values are consistent with the relationship

However,thesevaluesshouldbeveryinfluencedbythelocationofthevibrationallevelsofthe B1+
state, because the difference in energy between the A and B states is very similar to the vibrationalintervals. The dominant electronic configurations for the X1+, A1, and B1+ states are
X1+ : (core)(13 )2(14 )2(7 )4(3)4(15 )2(8 )4
A1 : (core)(13 )2(14 )2(7 )4(3)4(15 )2(8 )3(16 )1
B1+ : (core)(13 )2(14 )2(7 )4(3)4(15 )1(8 )4(16 )1
Considering these electronic configurations, we can estimate qv from our RKR potentials and the simplepure precession theory:
qv =
v
2l (l + 1)v |B(r)| v
2Evv
(9)
Considering the interaction between the pure A and pure B states and taking the matrix element< v|B(r)|v > into account, one can calculate the theoretical lambda-doubling constants for eachvibrational level. Three calculations were carried out:
(a) only considering the vibrationally diagonal term, and l = 2 (calc1),
(b) considering |v| < 6 and l = 1 (calc2), and
(c) considering |v| < 6 and l = 2 (calc3).
We found that calc1 was unsatisfactory and that our observed values are approximately equal to (calc2)and one third of (calc3). Because the electronic configurations come from the excitation of a 3delectronon Cu+, l should not be 1 but should have a value of 2. However, our calculation does not reproducethe values ofqv with l = 2. This effect was also seen in CuF [5] and CuCl [38].
Delaval et al.discussedthe originof these differences between theobserved parameters andpredictedvalues from the pure precession model in the case of CuF [18]. One possibility is that the actual valenceelectron (or hole) has not only the 3d character of Cu+ but also 3p character of the ligand Br ion.This means that l could have a value between 1 and 2. Secondly, because the 1 state also interactswith other states such as C1 and b30 through homogeneous and heterogeneous interactions [39],the pure A1 state is already corrupted. Thirdly, because the ground state rises from the Cu+(3d10)configuration, configuration interaction between the ground and the B state reduces the Cu+(3d94s)character of the B state. This configuration mixing was also predicted by the latest ab initio calculationsby Sousa et al. [29].
This third mechanism can be tested by assuming that the actual ground and B states are simplyrepresented by linear combination of pure ground and B state wave functions, while the A state is
perfectly pure. The other states like the C1
and a3
states are assumed to interact weakly with theA1 state. The corrupted wave functions for the ground and B states,X1+ and B1+ would
beX1+ = b X1+ + 1 b2 B1+ (10)B1+ = 1 b2 X1+ + b B1+ (11)where b is the mixing coefficient, and
X1+ and B1+ denote pure basis functions for the groundand B state, respectively. The pure precession formula between the A state and corrupted B state

By using formula (12) and l = 2, we obtain b2 = 0.842, 0.782, 0.714 for v = 0, 1, 2, respectively,using approximate RKR potentials generated by using the constants of Table 2. These mixing ratiosare consistent with the ab initio value, 0.76 [29]. The observed effective l values are approximately thesame, consistent with configuration mixing of the X1+ and B1+ states.
5. Conclusion
We have recorded new Fourier transform emission spectra of the A1 X1+ and B1+ X1+transitions of CuBr. Bands with v = 02 and v" = 03 were rotationally analysed to obtain improvedspectroscopic constants. The -doubling in the A1 state was interpreted in terms of interaction withB1+ state.
