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 surface-enhanced Raman spectroscopy ( SERS ) of g-aminobutyric acid ( GABA ) adsorbed on silver colloids in H 2 O and D 2 O were recorded and analyzed. When the concentration is greater than 10 03 M , the adsorbed species is the anionic form of the amino acid that interacts with the surface thro
The ~1 (CN) band of SCW in acetonitriie solvcnr has been observed, surface enhanced, at a silver electrode. Adsorption through the S of SCK is suggested. The changes of frequency and intensity with the change of electrode potenti& are reported. The u(CN) band of the solvent is also probably enhanced
