T. Luty et al., PHENOMENOLOGICAL THEORY OF ELECTRON AND METHYL TRANSFER-REACTIONS IN ORGANIC-CRYSTALS, Molecular crystals and liquid crystals science and technology. Section A, Molecular crystals and liquid crystals, 240, 1994, pp. 259-267
A model description of intermolecular electron transfer and intramolec
ular electron transfer (and related to it methyl transfer) reactions i
n organic solids are discussed. As a first step towards quantitative m
odeling of the reactions we construct potential energy surface in the
phonon normal coordinates space. A role of coupling of the transferred
electron to intramolecular vibrations and excitons which determine di
electric properties of the crystal is stressed. Transformations ''neut
ral-ionic'' in TTF-Chloranil and zwitterion formation in Methyl p-Dime
thylaminobenzenesulfonate are discussed as examples.
