Abstract
The continuous-time-random-walk (CTRW) model which was developed for electron scavenging reactions in polar glasses is extended to the phenomenon of spectral relaxation of electrons in shallow traps et− in a wider range of systems. The central role of electron-phonon coupling in understanding the initial electron localization, the "pre-existing trap", and electron transfer processes are emphasized. The reactivity of et− with scavengers, including protons, is discussed in terms of the theory of multi-phonon non-radiative transitions.
