The wavelength dependence of surface enhanced Raman (SER) scattermg from pyndme on a copper electrode surface has been measured and found to correlate closely wrth the optrcal propertres of copper metal. The results are interpreted III the hght of the image field model of the SER mechanism.

The voltage dependence of the SER spectra of adsorbed ATP molecules has been found to vary with the pH values of the solutions. The differences in the spectra are explained by the protonation of the adsorbed ATP molecules.
