A major part of the giant Raman scattering by adsorbed molecules on a Ag-island film is shown to be due to the large increase in the electric field at the molecules and to the large electric dipole moment of the molecule-metal-island complex that result from the excitation of the transverse collective electron resonance of the film.
Chen et al. (1980) studied this question.
