The UV-Vis, pre-resonance Raman and IR spectra of the complex (Cy3P)2Pt=SiMes2 (1) were obtained as well as Raman spectra of some model compounds. The experimental data and the results of normal coordinate calculations show that the stretching vibration of the Si?Pt bond in 1 is not localized, the nuSi=Pt internal coordinate makes significant contribution to two normal modes with frequencies at 465 and 612cm-1, whose Raman intensity is enhanced by pre-resonance.
获得了配合物(Cy3P)2Pt=SiMes2 (1)的紫外可见光谱、预共振拉曼光谱和红外光谱，以及一些模型化合物的拉曼光谱。实验数据和正则坐标计算结果表明，1中Si?Pt键的伸缩振动不是局域化的，νSi=Pt内坐标对频率分别为465和612cm-1的两个正则模式有显著贡献，其拉曼强度因预共振而增强。
