Experimental evidence is given for surface complexes consisting of metal-adatom, pyndme and halide ions with which the surface enhanced Raman process can occur. A large part of the enhanced continuum turns out to result from a superposition of numerous extremely weak SER hnes attributed to these com
Raman spectra have been obtained for sub-ML coverages of Cbo on cold-deposited Ag surfaces. The enhancement of these spectra persists upon annealing of the surfaces to z 300 K, unlike typical surface-enhanced Raman scattering (SERS) spectra. After annealing, the Cm spectra have an excitation profile
A model for Raman scattering from molecules chemisorbed on surfaces is proposed. It is shown that part of the en hancement may be due to charge-transfer eucitatrons between the metal and the adsorbed molecules. A photon, incident upon a gas-phase molecule, may be inelastically scattered, leaving th
