Abstract

Measurements are reported of the surface core level shifts of the clean Rh(110) surface, the clean metastable (1 × 2) surface, and NO and oxygen covered surfaces. The shifts are discussed in terms of a Born-Haber cycle formalism, and also within an initial state model of charge transfer after adsorption. Thermodynamic data are derived and it is shown that the heat of adsorption of NO is higher on Rh than on Pd. In addition, the valence level electronic structure of NO adlayers has been examined by Cooper minimum spectroscopy, and the molecular orbitals of NO, adsorbed oxygen and adsorbed nitrogen are reported. Near edge X-ray absorption spectra (NEXAFS) of molecular NO are reported, and the molecule is found to be adsorbed with its axis normal to the surface. © 1993.
