Molecular level electronic information obtained using ultraviolet photoelectron spectroscopy (UPS) is presented for titanium-dioxide-bound organometallic complexes produced in the ultrahigh vacuum (UHV) environment. These covalently bound organometallic complexes are produced by reacting the hydroxylated TiO2(001) low temperature facetted surface with vapor of tris(allyl)rhodium. UPS, AES, and ELS data for this species, as well as for the di(allyl)rhodium oxide-bound species and the product of its hydrogenation are presented. The UPS data indicate that 2p electrons originating from the oxygen of the support have a lower BE peak maximum for the rhodium hydrides than for the di(allyl)rhodium bound species.
