Abstract
Classical, semiclassical, and quantum theories of outer-sphere electron-transfer reactions in polar media are discussed. For each, the Franck-Condon overlap factors for the hexaamminecobalt, hexaaquoiron and hexaammineruthenium self-exchange rates and for the Fe2+-Ru(bpy)33+ cross-reaction are evaluated and compared. The quantum effect on the rates is relatively unimportant in the “normal” AG° region. Direct sum and saddle-point evaluations of the quantum Franck-Condon factors are made and compared.
