A determination of adsite symmetry on surfaces via electron energy loss spectroscopy: Coadsorption of CO and NO on Ru(001)

Abstract
Electron energy loss spectroscopy has been used to study the vibrational energies of NO and CO coadsorbed on the Ru(001) surface. Adsorption of CO competes directly with adsorption of one of the two molecular states of NO. This is interpreted in terms of the geometry of the adsorption sites for CO and NO and is consistent with models proposed previously for adsorption of CO and NO separately on the Ru(001) surface.
