Abstract
Near edge X-ray absorption fine structure (NEXAFS) spectra of 2-mercaptoben zoxazole adsorbed on the Pt(111) surface have been investigated for differe nt layer thicknesses at 95 K. By comparison of the NEXAFS C K-edge spectra for multilayer, three layer and monolayer and with the support of ab-initio static-exchange calculations, the change of molecular orientation vs. laye r thickness is discussed, and a possible adsorption mechanism for MBO on Pt (111) is proposed.
