Abstract
Studies of surface-enhanced Raman scattering from pyridine adsorbed on Ag surfaces in ultrahigh vacuum show a strong dependence on both surface roughness and pyridine coverage. The observation of enhancement (104) for physisorbed pyridine multilayers in addition to the first molecular layer implies that the enhanced effect is electromagnetic rather than chemical in origin.
