Abstract
The paper discusses the physical reasons for temperature effects in the absorption spectra of solvated electrons es − in polar liquids. A self-consistent calculation has been performed on the contributions to the temperature-dependent shift in the absorption line from frequency effects in the model for a continuous dielectric medium with an es − polaren state, i.e., on changes in the properties of the medium in the ground and excited states of es − as a result of collective fluctuations in the electron charge and polarization of the medium. It is shown that these effects cannot explain the observed large shift. A qualitative description can be given of es − in discrete-model language as localized states in microstructures, which enables one to consider the observed shift as due to temperature-dependent change in the equilibrium populations of such structures.
