文摘The coherent potential approximation (CPA) was used in the calculation of the vibrational spectra for absorbed 12CO/13CO thextures 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 Anxtures of CO on Pt(001), molecules interact mainly through their dipole fields.
