摘要：
The unusually large Raman signals originating from molecules adsorbed on electrode surfaces are postulated to arise from resonance enhancement by electronic processes at the rough metal-eletrolyte surface. By modelling this transition region between metal and eletrolyte with a collection of metallic spheres surrounded by adsorbate and ambient medium on top of a flat metal substrate, satisfactory agreement is obtained between measured and calculated spectra of both ΔR/R and the excitation function of the Raman signals. © 1979.
