Abstract

A normal mode analysis of experimental data from helium atom scattering (HAS) and electron energy loss spectroscopy (EELS) for vibrations of CO molecules adsorbed in on-top and bridge sites on Ni(100) is presented, using a refined force-constant analysis. The similar case of CO adsorbed on Pt(111) is reinvestigated, revealing a misassignment of normal modes in previous work. Finally, available experimental data for CO on Pt(111) is used to construct a trial potential energy surface.
