Abstract:

The coherent potential approximation (CPA) was used in the calculation of the vibrational spectra for absorbed 12CO/13CO mixtures on platinum. The theoretical results were compared with the surface IR-spectra of 12CO/13CO mixture absorbed on Pt-electrode. The results show that in the systems consisting of isotopic mixtures of CO on Pt(001), molecules interact mainly through their dipole fields.

Key words: Dipole-dipole interaction, Coherent potential approximation, Intensity transfer, Frequency shift
