The enhancement of Raman scattering (RS), resonance Raman scattering (RRS), and fluorescence from molecules adsorbed en silver-lsiand films is reported. A helrarchy of enhancements 1s found: 10 for RS, 10 for RRS, and 0.1-10 for fluorescence, depending on the quantum yield of the free molecule. Using the framework of the electromagnetic theory of surface-enhanced Raman scattering, generalized t...
