Sm. Pimblott et Ja. Laverne, ON THE RADIATION-CHEMICAL KINETICS OF THE PRECURSOR TO THE HYDRATED ELECTRON, The journal of physical chemistry. A, Molecules, spectroscopy, kinetics, environment, & general theory, 102(17), 1998, pp. 2967-2975
Comparisons of the predictions of stochastic diffusion kinetic calcula
tions using electron track structures with experimental scavenger data
show that the precursor to the hydrated electron, e(pre)(-), plays a
role in determining the total yield of electrons scavenged in a number
of systems. The significance of e(pre)(-) scavenging on yields depend
s on the scavenger of interest and on the rate coefficient of the scav
enger's reaction with the hydrated electron, e(aq)(-). For Cd2+, where
the reaction (e(aq)(-) + Cd2+) is fast, the consequences of e(pre)(-)
scavenging are experimentally not apparent, for NO3-, a less efficien
t e(aq)(-) scavenger, the effects of e(pre)(-) reaction are apparent i
n concentrated solutions, and for SeO42-, an inefficient e(aq)(-) scav
enger, e(pre)(-) scavenging is obvious even in dilute solution.
