Chemical
transformation of one molecular entity caused by
photoexcitation of a
sensitizer,
which undergoes
temporarycovalent bond formation with the molecular entity (M).
Notes:
- This mechanism is the basis of the Type I photooxygenation.
- The reactive molecular entity could be ground-state molecular dioxygen,
O2, in
which case energy transfer may occur producing singlet molecular oxygen,
this being the basis of the Type II photooxygenation.
