The adsorption of hexene(C6H12)on Ru() surface has been studied by the polarized angleresolved ultraviolet photoemission spectroscope (ARUPS) and Xray photoemission spectroscope (XPS). The results show that the hexene absorbs in a molecular state on the Ru() surface below 200 K,the molecular orbits of πCC,σCC and πCH were found at 7.5,9.4 and 11.1 eV respectively.The results of the polarized ARUPS show that the σCC orbit is symmetry about a mirror plane along <> azimuth but the πCC orbit is antisymmetry about a mirror plane.The results suggest that the hexene molecule lies in a plane along <> azimuth.With warming the substrate to 200 K the πCH molecular orbit increases 0.2 eV in binding energy,and the C 1s core level decreases 0.3 eV in binding energy,the results suggest that dehydrogenated of hexene occurs at 200 K.
