One mole of
photons is known as one Einstein of radiation. According to Stark-Einstein law
of photochemical equivalence, one mole of reactant absorbs one Einstien of energy. For a
photochemical reaction, a term called quantum yield is defined as:
Quantum yield (ϕ)=No.ofmolesofreactantconvertedNo.ofEinsteinabsorbed
