We present in this paper the study of surface enhanced Raman scattering (SERS) spectra of imidazole adsorbed on the electrochemical roughened silver electrode surface in nonaqueous methanol and the potential and laser luminous time dependence of the SEBS spectra. We also detected the morphology of the silver electrode surface and studied some mechanism of SEBS effect of imidazole adsorbed on the silver electrode in nonaqueous system.
