Effect of Low Illumination during Oxidation-Reduction Cycles upon Surface-Enhanced Raman Scattering from Silver Electrodes.

摘要

The intensity of surface-enhanced Raman scattering from thiocyanate and chloride adsorbed at silver electrodes is shown to depend critically on whether the electrode is illuminated during the oxidation-reduction cycle (ORC) used to pretreat the electrode. The nature and magnitude of the photoeffect is dependent upon the type of surface vibrational mode, the adsorbate, and the wavelength of the irradiation during the ORC. (Author)
