摘要：

The electronic structure of the surface carbonate species adsorbed on Ag{110} has been studied with angle-resolved photoemission using synchrotron radiation. Despite the low symmetry of the surface complex (C(s)) and more than one azimuthal orientation of the vertical symmetry plane, it has been possible to assign the adsorbate-induced levels. Recent semiempirical quantum chemical calculations have proved to be of considerable assistance in this process. The resonant behavior observed for the 3a" level is discussed in the context of photoelectron data for the free BF3 molecule, which is isoelectonic with CO3(2-). The C(s) symmetry pertaining in the present experiment is compared with the effective D3h symmetry observed in x-ray-absorption spectroscopy of the same system.
