✦ Synopsis

The short-range component of SERS IS tnvcstigated usu-~g a new probe molecule, lhlourca Through a study of the chxactcnstics or thiourea ndsarbcd on a sliver clectrodc we conclude that remnant surFace complexes arc not a un~vcrul rcquircment for large enhancement. We lurther show that the npphul voltage deriitely influcnccs the cnhanccmcnt Tar irdlvidual thlourca molecules 1 Inboductlon Several aspects of surfaceenhanced Raman scattering (SERS) are not yet resolved. Although electromagnetic field enhancement, which influences molecules some distance away from the metal surface, can be

The surface-enhanced Raman (SER) scattering of p-nitroaniline adsorbed on silver colloids was investigated and compared with previous results obtained on a silver electrode. The SER spectra change signiÐcantly on varying the pH of the colloidal dispersions and correspond to di †erent adsorbed specie
