✦ Synopsis


We analyse outer-sphere electron transfer (ET) in a dielectric medium, which is characterised by a continuous distribution of dielectric relaxation times. An explicit expression for the averaged ET rate is derived in the particular case of the Davidson-Cole dielectric susceptibility function. A quantitative account of recent experimental data for ET in the Ru(phen#+ methylviologen*+ system in glycerol is provided.

An unusually strong temperature dependence on the intramolecular eiectron-transfer rate has been observed for bridged donor-acceptor compounds in propylene glycol solution. In the frame of recent electron-transfer theories this effect reflects the influence of dielectric relaxation dynamics on elect
