The attenuated total reΓection (ATR) method was applied to obtain the Γrst layer enhancement in the case of pyridine adsorbed on Cu(100), ( 111) and ( 110) and a (110) vicinal surface, the values being 3, 19, 40 and 83 respectively. By comparison of the Raman bands and the enhancement at the Cu(111)

The surface enhanced Raman scattering (SERS) of pyndtne adsorbed on a copper electrode was observed with 647 1 nm ercztatlon and the dependence of the Raman tntenslty as a fun~on of electrode potential was obtarned for the most mtense bands The results are compared with reported mtenslty and frequen
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
