Long and short range effects in surface enhanced Raman scattering

Surface plasmon polariton enhanced Raman scattering, from molecular monolayers adsorbed onto continuous Ag surfaces at 300 K and low temperatures, has been studied. The observed spectra, at the multilayer level, are similar to the Raman spectra of the condensed bulk. The first layer scattering shows changes in both the scattering intensity and the spectral features similar to those seen in surface enhanced Raman experiments using substrates prepared in other ways. © 1982 American Institute of Physics.
