The temperature dependence of near-edge x-ray absorption fine-structure spectra above the C K edge and S L/sub 2,3/ edge for thiophene (C/sub 4/H/sub 4/S) on Pt(111) reveals changes in the chemisorption geometry and the cleavage of the carbon-sulfur bond. Our results suggest the formation of a metallocycle intermediate after desulfurization with the S atom replaced by a Pt surface atom. The near-edge x-ray absorption fine-structure results are corroborated by thermal desorption, x-ray photoemission, and electron-energy-loss data.
