Zusammenfassung

A mechanism is described whereby the influence of an external magnetic field on the sublevels of a triplet exciplex, subject to heavy-atom-induced sublevel-selective deactivation, modulates the radical dissociation yield of the exciplex. A sublevel selection rule for the heavy atom effect on T1 - S0 intersystem crossing in the triplex exciplex is derived. The magnetic field influence is treated on the basis of an approximate solution of a stochastic Liouville equation, leading to a simple analytic expression for the magnetic field effect on the radical yield. The result is applied to explain a previously observed magnetic field effect. The mechanism described may induce magnetic field effects on any triplet reaction competing with sublevel-selective deactivation.
