✦ Synopsis

Abstmct4neelectron

oxidation of phenothiazine to the corresponding radical cation was used as a model system to study the solvent effect on the heterogeneous charge-transfer kinetics. The standard rate constant of the studied electrode reaction was found to depend considerably on the nature of the solvent. The experimental kinetic data has been interpreted in terms ofthe dielectric dynamic properties of the solvent. The linear relationships between the standard rate constant and the reciprocal of the longitudinal dielectric relaxation time of a given solvent have been found in the aprotic case as well as for hydrogen-bonded solvents. The difference between both groups of sokents may be explained by the different dielectric relaxation b&&our or by the difference in the reaction site in respect to the electrode surface.
