β¦ Synopsis
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 complexes.
