Grotthuss-Draper law:
Only the light absorbed in a moleculecan produce photochemical Change in the molecule(1871 and 1841)
Stark - Einstein:
If a species absorbs radiation, then one particle is excited for each quantum of radiation absorbed
Stark - Einstein:
If a species absorbs radiation, then one particle is excited for each quantum of radiation absorbed
QUANTUM YIELD:
Φ = The number of molecules of reactant consumed for each quantum of radiation absorbed
Primary Φ ≤ 1Sum of all primary Φ’s =1
