Preferred Label : photochemical equivalence;
IUPAC definition : According to the principle of photochemical equivalence, there is a one-to-one relationship
between the number of photons absorbed by a system and the number of excited species
produced. The principle often fails for light of high intensity (e.g. laser beams),
when molecules may absorb more than one photon.;
