Enhanced Raman Scattering from Benzene Condensed on a Silver Grating

Abstract
We study the Raman intensity from a benzene overlayer on a silver grating as a function of layer thickness both in theory and experiment. Numerical results are obtained using matrix formalism based on the Rayleigh method for a coated grating. The electromagnetic enhancement due to surface plasmon polariton resonances and multiple beam interferences for a p-polarized incident wave is discussed.
