Abstract:

The coherent potential approximation (CPA) is used in the calculation of the vibrational spectra for absorbed 12CN- /13CN- mixtures on gold. The theoretical results are compared with the surface IR-spectra of 12CN-/13CN- mixture absorbed on rough Au-electrod. The results show that in the systems consisting of isotopic mixtures of CN-on Au(100), molecules interact mainly through their dipole fields.

Key words: Dipole-dipole interaction, CPA, Intensity transfer, Frequeney shift
