VIBRATIONAL SPECTRUM OF $DISLANE^{*}$

Abstract

Raman spectra of the liquid and infrared spectra of the gaseous phase have been obtained for both $Si_{2}H_{6}$ and $Si_{2}D_{6}$. With the exception of the torsional mode all fundamental frequencies have been observed and assigned to the proper normal modes. The coarse rotational structure of the perpendicular bands has been resolved and the corresponding Coriolis coupling coefficients determined. Comparisons with the spectra of ethane and methyl silane have been made.
