Abstract

The infrared (3500–40cm− 1) spectra of gaseous and solid 1-methylsilacyclobutane, c- C3H6SiH (CH3), have been recorded. In addition, the Raman spectrum (3500–30cm− 1) of the liquid has also been recorded and quantitative depolarization values obtained. Both the axial and equatorial conformers, with respect to methyl group, have been identified in the fluid phases. Variable temperature studies (− 55 to− 100° C) of the infrared spectra of the ...
