摘要: Near edge x-ray absorption spectroscopy is now being used to obtain information on the geometry and chemical bonding of adsorbed species [1,2]. In cases where adsorbate not known with certainty it useful be able compare experimental near spectrum a calculated for model systems representing various possible configurations species. I describe in this paper general technique computation structure adsorbates within framework Scattered Wave Xα method illustrate application by calculation at carbon K ethylene ethylidyne (CCH3) Pt(111).
