Methylviologen adsorbed on a roughened silver electrode is reduced to its cation radical upon irradiation with laser light at liquid nitrogen temperature. Surface-enhanced Raman scattering (SERS) spectra were obtained with different excitation wavele

Surface-enhanced Raman scattering (SERS) from molecules adsorbed on rhodium-modified colloidal silver particles is reported for the first time. Deposition of thin layers of metallic rhodium on the silver surface led to fast aggregation of the sol and

Surface-enhanced Raman spectra (SERS) of acetylene adsorbed on rhodium- and platinum-modified silver and on rhodium-modified gold were determined at room temperature in both acidic and neutral supporting electrolytes. In acidic media the spectra exhi
