- Improved adsorption characteristics of a K predosed Cu(110) surface with a coverage corresponding to a point before the work function minimum have been confirmed. Analysis of the CO-induced orbitals in the photoelectron spectra of the CO/K/Cu(110) interface for low coverages of carbon monoxide adsorbed at 118 K has been done. Noticeable changes of the parameters of the orbitals with increasing CO coverage have been registered. Elongation of the C-O bond without dissociation of the molecule has been deduced from the energetic separation of 3.4 eV between the 4σ and the 1π orbital. A weakening of the CO-interface bond with coverage has been found on the base of decreasing 5σ-1π separation with increasing 4σ/5σ intensity ratio. Perpendicular orientation of CO molecules to the plane of the substrate surface has been concluded from analysis of the constant initial state spectra of the 4σ and 5σ/1π orbitals.
