Cj. Calzado et al., PHYSICAL FACTORS GOVERNING THE AMPLITUDE OF THE ELECTRON-TRANSFER INTEGRAL IN MIXED-VALENCE COMPOUNDS, The journal of physical chemistry. A, Molecules, spectroscopy, kinetics, environment, & general theory, 102(21), 1998, pp. 3659-3667
This paper first reviews the various methods of calculation of the tra
nsfer integral in mixed valence compounds. The different physical effe
cts affecting the electron transfer, namely overlap, through bond delo
calization, relaxation and polarization of molecular orbitals, and cor
relation contributions are described and discussed. Illustrative model
problems are proposed, and the ability of the various treatments to i
ncorporate these physical effects is studied.
