Partitioning technique in electron transfer and excitation energy transfer

Abstract

Abstract The partitioning technique of Lowdin is used to derive practical and useful models for the mediation properties of matter in electron transfer (ET) and excitation energy transfer (EET). Partitioning technique is first used on the many-electron level for EET, where direct as well as mediated Forster and Dexter coupling is treated. Corresponding equations for ET, referred to as “superexchange” models, are derived. ET is also treated on the one-electron level, where the connection between ET capability and structure is discussed. A practically useful procedure to calculate the electronic factor on a PC screen in large systems is described. Finally the usefulness of models derived from partitioning technique is critically assessed.
