Abstract

The surface-enhanced Raman scattering (SERS) and resonance Raman scattering (RRS) enhancement mechanisms have been exploited In obtaining surface Raman spectra from the adsorbed anion of dlthizone (diphenylthiocarbazone) at a silver electrode surface at -0.20 V (vs, Ag/AgCI) In pH 12 aqueous alkaline buffer solution. SERS+RRS spectra with acceptable signal-to-noise ratios were acquired from solutions initially 10-2 M through 10-9 M In dlthizone anion. The SERS+RRS-detected adsorption isotherm is presented. Calculations of surface population based on the suggested orientation of dlthizone anion at the silver surface allow a mlnimumi SERS enhancement factor of 2 X 103 to be estimated for this system.
