| 摘 要： | 利用角分辨紫外光电子能谱对低温下（160 K）乙炔（C2H2）气体在Ru()表面的吸附 进行了研究.实验结果表明：乙炔的C-C轴并不平行于衬底表面, C-C轴在<0001>晶向和表 面法线组成的平面内有一定的倾斜.与气相乙炔分子不同,在Ru()表面吸附的乙炔分子的C-H 轴不是沿C-C轴向.

| 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. |
