Abstract
The influence of coadsorbed potassium atoms on the electronic structure of CO adsorbed on Ni(111) was studied by use of surface metastable quenching spectroscopy. An enhancement of electron emission from the partially filled antibonding orbital of CO is observed, and the result is interpreted in terms of increased electron back-donation from the metal to the orbital, caused by potassium atoms.
