Abstract : The ultra-fast, second-order decay of the hydrated electron, e(aq)(-), first observed following nanosecond X-ray pulses in air-free, alkaline solution, has been studied in greater detail. The addition of alkali halide salts in low concentration strongly influences the kinetic behavior of the reaction, and it is suggested that e(aq)(-) reacts with a positive ion, tentatively assigned the formula H2O(+). The effect of structure on reactivity is discussed and methods of charge transfer and energy migration in solution are reviewed. The possible existence of a Wannier exciton in these solutions is suggested. (Author)
