Abstract

Consideration of current information on the dependence of the electron transfer rate on the radial separation distance and on the reactantsβ€² radial distribution function suggests for adiabatic transfers a frequency factor closer to 10^12^M^βˆ’1^ s^βˆ’1^ than to 10^11^M^βˆ’1^ s^βˆ’1^. One effect is to raise the Ξ» values estimated from self‐exchange rate constants, and to extend thereby the range of Ξ”__G__Β°'s in which the β€œinverted region′” is masked by a diffusion‐controlled reaction rate.
