This paper addresses the conceptual framework of femtosecond nonadiabatic dynamics involving electron transfer processes on the time scale of nuclear motion. Coupling and relaxation of a manifold of doorway states into a weakly correlated Franck-Condon quasicontinuum reflects the extension of the validity range of nonadiabatic dynamics for large values of the electronic coupling, transcendenting the vibrational period of nuclear motion. The theory is applied to ultrafast femtosecond electron transfer processes in solution.

In situ spectroelectrochemical studies focussing on the Franck-Condon region and sub-ns electron transfer processes in Ru(II)-tpphz-Pt(II) based photocatalysts reveal that single-electron reduction effectively hinders intramolecular electron transfer between the photoexcited...

Electron Transfer Processes

Electron transfer processes in He+–Na(3s, 3p) collisions are studied with the semiclassical close-coupling method. The electron dynamics is described with a number of antisymmetrized two-electron configurations of atomic-orbital type. Contrary to assumptions in earlier work, capture to the 31,3L He states is found to be important in the keV energy region. The calculated transfer cross sections agree well with recent data on Na(3p)–Na(3s) cross-section ratios and on the Na(3p0)–Na(3p1) anisotropy parameter.

Enol ↔ keto prototropic tautomerism can be exploited to modulate the photophysics of BODIPY chromophores based on proton-coupled photoinduced electron transfer processes.
