Abstract:
Analysis of scanned-energy mode photoelectron diffraction data from NO adsorbed on NiO(100) confirms that both components of the N 1s photoemission doublet observed for this system do originate from the same surface species, and provides a quantitative determination of the local adsorption geometry. NO is found to adsorb N atom down ontop a Ni atom, with a N–Ni bond length of 1.88±0.02 Å. The N–O bond is tilted away from the surface normal by 59(+31/−17)°.
