ResumoLaviron's theoretical treatment of cyclic voltammograms for redox species confined to the electrode surface was modified so as to clarify the experimentally accessible physical quantities. The resulting equations were applied to the analysis of the redox-electrode reactions in acidic media of surfactant polypyridine osmium and ruthenium complexes, M(I:/III)(ndbpy), where M = Os or Ru, bpy = 2,2′-bipyridine and ndbpy = 4,4′-dinonadecyl-2,2′-bipyridine, confined to the surface of SnO2 electrodes in a monomolecular layer by the Langmuir—6Blodgett method. The deviations of the experimental voltammograms from an ideal “surface wave” could be interpreted by taking into account the interactions among the adsorbed reactants.
