Abstract: | Singlet oxygen chemistry and photo-oxidation reactions, in general, often require one or more critical reaction steps that involve an intersystem crossing from a singlet state to a triplet state or vice versa. This paper considers two important intersystem crossing mechanisms, electron spin-electron orbit (spin-orbit) coupling and electron spin-nuclear spin (spin-spin) coupling, and how they may be involved : (1) in the deactivation of 1O2 to 3O2 ; (2) in the thermal catalytic conversion of 3O2 to 1O2; and (3) in the fragmentation of aromatic endoperoxides to yield O2 and an aromatic substrate. |
