ABSTRACT We present the first experimental results which demonstrate a quadratic relationship between the enhanced Raman scattering from molecules on Ag surfaces and roughness-coupled surface-plasmon radiation. These results are Interpreted by a model which includes both roughness assisted surface-plasmon scattering and radiative coupling.
