Abstract
The C-H stretch vibrational modes of O chemisorbed on a Cu(100) surface have been studied using infrared spectroscopy. Three absorption peaks were found indicating that the symmetry of the group is broken. Comparison with the infrared spectra of free methanol shows that the O group is rather little perturbed by the chemisorption and that the molecules definitely are tilted on the surface. Thermal desorption spectra indicate that the dehydrogenation of O to CO goes via the adsorption of a hydrogen atom on the copper surface during a low frequency bending mode.
