The Raman and IR spectra of chloromethylmethylchlorosilanes ClCH2SiCl3, ClCH2CH3SiCl2, and ClCH2(CH3)2SiCl were measured. The frequencies, degrees of depolarization, widths, and standard intensities of the lines were determined in the Raman spectra, and the positions of the bands and the qualitative intensities were determined in the IR spectra. The assignment of the frequencies to the normal vibrations is discussed.
An analysis of the electronic structure of the various conformers of the molecule was made by the quantum-chemical CNDO/2 method with allowance for the d orbitals of the silicon atom.
The possibilities of mutual influence of the silicon and chlorine atoms in the
group are considered.
