The process by which a photochemical or photophysical alteration occurs in one molecular
entity as a result of initial absorption of radiation by another molecular entity
called a photosensitizer
. In mechanistic photochemistry
the term is limited to cases in which the photosensitizer
is not consumed in the reaction.
