Raman spectra of gases

The Raman spectra (50–1200 cm−1) of gaseous, liquid, and solid (Cl3Si)2O have been recorded. The infrared spectra of the gas and solid have been recorded from 55–2000 cm−1 . The spectra of the gas have been interpreted in detail on the basis of C2v symmetry with the A1 skeletal Si-O-Si bend assigned at 63 cm−1. The spectra gave evidence that there are structural changes upon condensation of the gas and the Si-O-Si angle approaches linearity in the solid state. The opening of this angle is probably due to crystal packing factors.
