Nitrous Oxide as a Scavenger in the Radiolysis of Water

Abstract

NITROUS oxide has been widely used as a specific scavenger for the solvated electron in the radiolysis of liquid water1–3; the rate constant for reaction (1) being greater than that for reaction (2) by a factor of 103 or more: N2O concentrations > 1.2 × 10−2 M have invariably been found necessary to obtain values of G(N2) independent of [N2O] despite the large magnitude of k1. Values of G(N2) = 3.0 ± 0.1 obtained with this high concentration of N2O have been equated to .
