The asymmetric broadening of the stretching vibration in surface enhanced Raman scattering of CO adsorbed on cryocondensed copper films can be explained by considering dipole-dipole interaction of the molecules and elastic scattering at structures of atomic roughness. Calculated line shapes are in good agreement with the experiment, including the low wavenumber shoulder. The variation of the line...
Surface-enhanced Raman scattering (SERS) spectra serve as a valuable source of information about the organic adsorbates at the surface and about the nature of the oxide films of monolayer thickness. In this study, interactions of 2-phenylpyridine and 3-phenylpyridine with copper surface were investigated by means of SERS spectroscopy and cyclic voltammetry and compared with 4-phenylpyridine. A strong...
