Abstract
Laser Raman spectra from the system: Cu/CH 3CN, NaClO 4, H 2O, reveal evidence for cyanocopper(I) species in the interfacial region. The cyanide appears to originate in the laser-assisted decomposition of coordinated acetonitrile in O 2-rich aqueous electrolyte. The evidence for the involvement of laser photochemistry comes from uniform laser-flux perturbations of the cyclic voltammetry for the system. Parallel studies for the corresponding silver electrode system reveal evidence for the exhaustive, and probably laser-assisted, electro-oxidation of acetonitrile into nitrates and carbonates.
