Vibration Spectra of Raman Scattering and IR Absorption of Certain Butoxysilanes,

Abstract

An experimental study was made of Raman scattering (RS) and infrared absorption (IR) of the compounds (CH3)3Si(OC4H9-n), (CH3)2Si(OC4H9-n)2, CH3Si(OC4H9-n)3, Si(OC4H9-n)4, Si(OC4H9-s)4, and Si(OC4H9-i)4. The frequencies, integral intensities, degrees of depolarization, and half-widths of the spectral RS lines were determined; corrected relative scattering coefficients were calculated, and finally, the values of the trace and the anisotropy of the tensor of the polarizability derivative were obtained. For three of the compounds the dispersion of the refraction index was investigated and the absolute cross sections of spontaneous Raman scattering were calculated for the Stokes waves v(s)(Si-O) and v(s)(Si-C). The absorption bands and, for individual vibrations, absolute intensities and half-widths were calculated in the IR. (Author)
