| Abstract: | The Raman, infrared and 1H-NMR spectra of (CH3)3 -X-Si (CH3)3 (X=O,S,Se,Te) were measured, and the assignment was carried out by comparison with those of the structurally related compounds, (CH3)3 SiCl and (CH3)3 Si-Si (CH3)3. The vibrational spectra of (CH3)3 Si-X-Si (CH3)3 can be interpreted in terms of a non-rigid D3d symmetry with internal rotations, because those of skeletones of the molecules indicate the lack of coincidence between Raman and infrared frequencies. The 1H-NMR spectra also support a non-rigid D3d model, because only one band for CH3 group appears. |
