The apparent heterogeneous rate constants can be determined by a special cu technique in solutions containing both the oxidized and the reduced forms of a redox couple. The electrode materials are characterized by the dikence between the ktX and kFed. The effect of RuO,/IiO, ratio on the electrochem

β¦ 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.

A study is made of the kinetic salt effects upon the outer-sphere electron transfer reaction between hexacyanoferrate(I1) and 4-pyridinecarboxylatopentaamminecobalt(III~. The observed salts effects are analyzed, taking into account the possible association of the reactants with the ions of the suppo
To assess the importance of the different time scales of non-Debye solvent relaxation on the reaction kinetics of electron transfer reactions we have performed a numerical simulation study for a model system of an activated solvent-controlled electron transfer reaction in the weakly adiabatic regime
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
