Electron transfer reactions between thiopyronine triplet (acceptor 3A+) and the electron donors (D), aniline, p-Br-aniline and p-I-aniline, are investigated by flash spectroscopy in solvents of different viscosity and polarity. Due to the heavy-atom effect the radical yield becomes very ~ensitive to the solvent influence, which can be explained by the dynamic properties of a triplet exciplex (3...

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 T, So intersystem crossing in the triplex exciplex is derived. The magnetic field influence is treated o...
