An analytic description of the cooperative effects of scavengers on the radiation chemistry of the hydrated electron in aqueous solution is developed by using the available experimental data and the results of deterministic diffusion-kinetic calculations. The formulation has two components: the first corresponds to the effect of the primary (electron) scavenger in isolation and the second represents the suppression of the e{sub aq}{sup {minus}} + OH spur reaction by the secondary (hydroxyl radical) scavenger. The two aqueous systems that have been considered in detail are nitrate/formate and nitrous oxide/2-propanol. The agreement between the analytic treatment, the experimental data, and the kinetic modeling is good. 37 refs., 7 figs., 2 tabs.
