Theory of the Solvated Electron in Polar Liquids. I. Oriented Dipole Model

Abstract

A model is proposed for the solvated electron in polar liquids, in which molecular dipoles are assumed to orient spherically around the electron. The potential field due to this orientation, the energy levels, the absorption peak and its temperature dependence, and the heat of solvation are calculated at various temperatures. Calculated absorption peak E = 1.69 eV (300°K), 1.89 eV (180°K), and ∂ΔE / ∂T = 0.16 eV deg−1 are compared with experimental data, and they show a fairly good agreement.
