Spin-Orbit Coupling in Free-Radical Reactions: On the Way to Heavy Elements

摘要

In this review article we have considered the manifestation of Spin OrbitCoupling in the elementary acts of formation and decay of exciplexes, radical pairs, biradicals, and other intermediates of importance to photochemistry. The major conclusion are that the spin orbit coupling acts in two ways, one promoting the magnetic field effect and the other quenching magnetic field effect, and that spin orbit coupling promotes magnetic field effect through two major mechanisms (triplet mechanism and delta g) and quenches the magnetic field effect creating a general sink for the spin coherency in a system....
