Spectral Properties of Pyrazine Adsorbed on Silver Electrodes and Cold Silver Films from Surface Enhanced Raman Scattering (SERS)

Abstract Surface enhanced Raman spectra of molecules adsorbed on electrode surfaces, metal-island films, colloidal particles and UHV-evaporated low-temperature substrates often show considerable differences in mode strength and positions between each other and the bulk molecular spectrum. These differences and their possible origins are discussed for pyrazine adsorbed on silver electrodes and cold silver films.
