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

The wavelength dependence of surface enhanced Raman (SER) scattermg from pyndme on a copper electrode surface has been measured and found to correlate closely wrth the optrcal propertres of copper metal. The results are interpreted III the hght of the image field model of the SER mechanism.
