Abstract

Scanned-energy mode C 1s photoelectron diffraction has been applied to the adsorption system of acetylene on Ni(111) to determine the local adsorption structure which is compared with the results of a similar study of acetylene on Cu(111). The adsorption site in both cases is with the molecule essentially parallel to the surface and in a crossed bridge site such that the two C atoms of the molecule occupy inequivalent hollow sites. A substantial, essentially identical stretching of the C-C bond relative to the gas phase is found for both surfaces (consistent with the interpretation of vibrational spectroscopic data), despite the marked difference in chemical reactivity of Cu(111) and Ni(111) towards hydrocarbons.
