The theory of solvated electrons is traced from its early origins. The successes and limitations of these treatments are discussed. An alternative viewpoint, which considers the local interactions between the surplus electron and the molecules in its immediate environment, is developed. Dimeric and tetrameric models for the excess electron in water and ammonia are proposed and investigated by way of semi-empirical molecular orbital theory. The peak positions calculated for the optical absorption spectrum of the electron in water, ammonia and ammonia-water mixtures are in fair agreement with experimental observations. Variations in peak position with pressure and temperature are in accord with experiment. Dilation measurements are suggested to be better accomodated by a lattice expansion than by cavity formation.
