Abstract

The surface-enhanced Raman scattering (SERS) behavior of HCN at polycrystalline Ag electrodes modified by monolayer and submonolayer amounts of underpotentially deposited Pb is presented. Changes in SERS intensity as a function of Pb coverage are interpreted in terms of preferential displacement of HCN from active sites by deposited Pb. By comparison with previous results obtained with pyridine and Cl^- as adsorbates in similar experiments, these data suggest that both large-scale and atomic-scale roughness features contribute significantly to the SERS intensities measured in these systems.
