Abstract: The acetylene (C2H2) adsorbed on Ru() surface has been studied by usin g angle-resolved ultraviolet photoelectron spectroscopy (ARUPS). The dependence of the σCC peak intensity on incidence angle and emission angle shows that C- C axis of acetylene（C2H2）is not parallel to the Ru() surface(see Fig.2). The C -C axis of acetylene is tilted in <0001> azimuth according to its symmetry(see Fig.3). Not as the acetylene in gas phase,the C-H bond of the acetylene adsorbe d on Ru () surface is not along the direction of the C-C bond.

Key words: Acetylene, Ru(1010) surface, Molecular orbit, Symmetry, ARUPS
