INFRARED AND RAMAN SPECTRA OF TRICHLOROSILYLISOCYANATE AND TRICHLOROSILYLISOTHIOCYANATE
Publisher:
Ohio State UniversityAbstract:
The infrared and Raman spectra of gaseous and solid $SiCl_{3} NCO$ and $SiCl_{3}NCS$ have been obtained over the frequency range of 20 to $4000 cm^{-1}$. The Raman spectra of the liquids have also been recorded. Assignments of the normal modes have been made on the basis of band types, Raman depolarization values, and characteristic group frequencies. The spectral data indicate that both $SiCl_{3}NCO$ and $SiCl_{3}NCS$ have quasilinear heavy atom skeletons in the fluid phases. The results will be compared to some other silicon pseudohalogen compounds recently studied.
