The spin dynamics of the duroquinone anion radical generated by photoinduced electron transfer reactions from triplet erythrosin B to duroquinone has been studied by using transient absorption and pulsed FT-EPR spectroscopy. Triplet exciplex formation as the reaction intermediate is verified by the observation of spin-orbit coupling induced electron spin polarization. The kinetic parameters for exciplex formation and the intrinsic enhancement factors of electron spin polarization are determined in various alcoholic solvents. The zero-field splitting constants of the triplet exciplex are determined by the analysis of the solvent viscosity dependence of the enhancement factors of the electron spin polarization.
