Geminate recombination exciplex dissociation

Fig. 4. Electron transfer quenching via exciplex formation, a exciplex emission b exciplex radiationless deactivation c geminate ion recombination. For sake of simplicity, processes such as exciplex dissociation into A + B, exciplex reactions other than the electron transfer one and direct formation of a solvated ion pair from the encounter complex have been omitted...

The spinless variant of the present theory was already discussed in Section V.D and its interrelationship with IET and a number of other theories of exciplexes or stable complexes was disclosed. In the next Section XI.D we also consider not an excited-state but a ground-state particle. It is subjected to thermal dissociation to radicals followed by their geminate and subsequent bimolecular recombination into the fluorescent product.
