Re-assignments of Valence Excitation Spectra with EELS of CO Adsorbed on Metal Surfaces

Abstract

Excited states of CO adsorbed on metal surfaces have been receiving considerable attention. Such states play important roles in a variety of surface dynamic processes, i.e., electron or photon stimulated desorption, etc.. Recent re-assignments of valence excitations with electron energy loss measurements of CO with metal surfaces have been discussed on the basis of the results calculated in terms of molecular orbital methods by Kawaguchi and Freund et al..
