Abstract :
Near edge X-ray absorption fine structure (NEXAFS) spectra of 2-mercaptobenzoxazole adsorbed on the Pt(111) surface have been investigated for different 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. layer thickness is discussed, and a possible adsorption mechanism for MBO on Pt(111) is proposed.
