The dynamics of proton transfer within the triplet contact radical ion pair of a variety of substituted benzophenones with N, N-diethylaniline, N, N-dimethyl-p-toluinide, and N, N-diallylaniline are examined in solvents of varying polarity. The correlation of the rate constants with driving force reveal both a normal region and an inverted region providing support for the nonadiabatic nature of proton transfer within these systems. The reorganization of both the solvent and the molecular framework are central in governing the overall reaction dynamics.
