It has been shown that the Si-F bond vibration interacts with the (CH3)3Si group vibrations in trimethylfluorosilane and its deuterated analog. It has also been shown that there is Fermi resonance between the Si-Br bond vibration overtone and the (CD3)3Si-group vibrations in deuterated trimethylbromosilane.
The results of vibration calculations on trimethylsilane, trimethylfluorosilane, and trimethylbromosilane show that the (CH3)3Si-group force-field model can be applied to the analysis of the spectra of these compounds.
