Dynamical Solvent Effects on Electron-Transfer Processes: Recent Progress and Perspectives.

摘要

Recent advances in theoretical and experimental aspects of dynamical solvent effects in activated electron-transfer processes are discussed, along with future research prospects. The last decade has seen a remarkable upsurge of interest in the dynamical role of the solvent in liquid-state chemical processes. Along with the intrinsic importance of such phenomena in chemistry and biology, these activities have been fostered by substantial recent developments of both a theoretical and experimental nature. The central concept of solvent 'friction', whereby the collective solvent motion necessary to surmount the activation barrier slows the rate below that expected from transition-state theory (TST), 1a-c has spawned a myriad of theoretical treatments that attempt to describe the effective solvation dynamics.
