Abstract
Solvated electrons were produced in several liquids by laser photoionization of aromatic solutes, and by pulse radiolysis. The yields of solvated electrons were decreased by high concentrations (0.1–1.0M) of phenol, benzene, and ethyl acetate; the effectiveness of the solutes in reducing the e−s yields was greater in the photolysis experiments than in the corresponding pulse radiolysis experiments. The data were, however, identical with light of wavelength 3471 or 2650 Å, from ruby and neodymium lasers, respectively. The data are used to discuss several theories. Solvated electrons in alcohols were photobleached with red light (λ=6942 Å) giving H atoms. The quantum yield for the process was found to be low.
