DIFFERENTIAL REACTIVITY OF EXCITED SINGLETS AND TRIPLETS.

Abstract

Experimental data from the oxygen quenching of excited states, from the acidities of excited states, and from the kinetics of photosynthesis indicate that the lowest excited singlet and the lowest triplet states of aromatic molecules may not have the same reactivity. The reasons for these differences may be connected with the energy deficit of triplets, with spin conservation rules, with differences in the nuclear geometry, or with differences in the electronic configuration or polarizability. With improved theoretical representations of excited states, the observed differences in reactivity may serve to increase our understanding of the nature of primary photochemical events. (Author)
