3. Theoretical Study of the Electronic Factor in Electron Transfer Reactions
Abstract : The electronic factor D is calculated for a number of organic and biological electron transfer systems. Quantum chemical methods at different levels of accuracy are used: ab initio Hartree-Fock, broken-symmetry, and correlation-corrected methods such as multiconfigurational second-order perturbation theory, and also the semiempirical CNDO/S method for very large systems.
