ULTRAFAST NONADIABATIC DYNAMICS - THEORETICAL-STUDY OF FEMTOSECOND ELECTRON-TRANSFER PROCESSES

This paper addresses the conceptual framework of femtosecond nonadiaba tic dynamics involving electron transfer processes on the time scale o f nuclear motion. Coupling and relaxation of a manifold of doorway sta tes ino a weakly correlated Franck-Condon quasicontinuum reflects the extension of the validity range of nonadiabatic dynamics for large val ues of the electronic coupling, transcendenting the vibrational period of nuclear motion. The theory is applied to ultrafast femtosecond ele ctron transfer processes in solution.
