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.
A new method for the preparation of SERS active Cu electrode surfaces with high enhancement factors, which enable the observation of high quality spectra in the low-frequency region at different chloride concentrations, is proposed. Low-frequency modes at 160 and 145 cm-t are attributed to Cu-Cu vib
