Chemical transformation of one molecular entity caused by photoexcitation of a sensitizer, which undergoes temporary covalent
bond formation with the molecular entity (M).
- This mechanism is the basis of the Type I @P04641@.
- 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 @P04641@.
