Enhanced Raman Scattering from Molecules Adsorbed at Metal Surfaces

Abstract

A microscopic theory for surface enhanced Raman scattering from admolecules is presented. The enhancement of the cross-section due to the presence of the metal is mainly due to two sources: (a) the renormalization of the electron-photon interaction vertex mediated by the surface plasmon mode; (b) the shift and broadening of the electronic levels of the molecule due to chemisorption and charge transfer. Contributions (a) and (b) are calculated as functions of the incident photon frequency and of the model parameters appropriate for a silver surface.
