Adsorbate-site determination by surface-state spectroscopy?
Electronic surface states can interact with adsorbate orbitals only if they have the same symmetry with respect to the adsorption site. This paper reports on the interaction of a surface state with adsorbate orbitals in the case of the molecular chemisorption system of Ni(110)/C(2)H(4)(-)c(2x4). Angle-resolved inverse photoemission (ARIPE) is used to investigate the unoccupied band structure of the Ni(110)/C(2)H(4)(-)c(2x4) adsorption system. The ARIPE is presented from a clean Ni(110) surface for different angles of electron incidence. Adsorption of a saturated layer of ethylene causes a suppression of most of the clean Ni features. The results are discussed in terms of symmetry properties and molecular orbital theory.
