The structure and/or distribution of products from the TiO2-sensitized photooxidation of some benzyl derivatives in aerated and/or deaerated aqueous media and in the presence of Ag2SO4 are reported. The results suggest that the single electron transfer process from the substrate to the photogenerated hole, previously proposed in CH3CN, should also be operative on gradually going from aqueous CH3CN to pure water.
Self-Termination and Electronic Spectra of Substituted Benzyl Radicals in Solution

Several substituted benzyl radicals have been generated in liquid cyclohexane by the photolysis of symmetrically substituted dibenzyl ketones.The rate constants for self-termination to substituted bibenzyls, and absorption spectra of the transient radicals, have been measured by optical modulation spectroscopy.The termination rates are generally well described by the von Smoluchowski equation with a spin factor of 1/4.Deviations are discussed in terms of steric retardation and the unreliability of the estimated reaction diameters of radicals with bulky substituent groups.Absorption spectra of the three monomethyl-, the three monochloro-, two dichloro-, and the three monomethoxybenzyl radicals demonstrate the influence of the substituents on the energy levels of the benzyl system.
