文摘SERS spectra of 2,5-dimethylpyrazine have been recorded on silver surface at different electrode potentials. The relative SERS intensities are compared with those of the Raman spectrum of an aqueous solution and the selective SERS enhancement has been explained according to a charge transfer enhancement mechanism.
