Angle-resolved photoelectron spectroscopy has been used to study the changes in the bonding of CO when coadsorbed with alkali-metal atoms. On metal surfaces [Cu(100) and Ru(0001)] various features in the photoemission spectra, including reduced site symmetry and a large shift of the 1π molecular orbital of CO, indicate a π-bonded configuration of the CO molecule. π bonding involves bonding through both the 1π and 2π* molecular orbitals of CO. All of the data indicate a short-range interaction between the K and CO.
