β¦ Synopsis
We show through enhanced Raman scattering from chloride on silver at large positive metal charge that the Stark effect and bond perturbation play minor roles in the potential dependence of the spectra. The major influence on the intensity and frequency of these spectra can be explained by charges ln surface coverage together with mutual depolarization effects.
