The potential dependence of the broad low frequency Raman scattering features from roughened silver electrodes and their Sensitivity to the chemical composition of the supporting electrolyte are presented. We find that the electromagnetic enhancement theories which relate these Raman bands to the vibrations of the silver surface structures are unable to account for all of the data electronic coupling to the stabilizing adsorabates requires that some of the charge transfer concepts of the adatom complex theories be included in the model.
