Abstract The electron transfer reaction between 9,lO-anthraquinone (AQ) excited to the lower triplet state and 1,2,4trimethoxybenzene (TMB) in solvents of different polarity has been studied by nanosecond time-resolved resonance Raman spectroscopy. In no solvent was there evidence for the formation of a triplet exciplex. All the observed vibrations were characterized as AQ* or TMB" modes. The frequency of the band assigned to the C-C stretch of TMB" has been found to be very dependent upon the environment and this effect has been used to observe the separation of the geminate ion pair into free ions in polar solvents. The data strongly suggest that the ions are at van der Waals contact in the geminate ion pair and not separated by solvent molecules.
