The pure‐rotational Raman spectrum of disilane

Abstract
From a study of the rotational Raman spectra of disilane and hexadeutero‐disilane the following rotational constants were determined: for Si2H6, B0 = 0.16998 ± 0.00003 cm−1; for Si2D6, B0 = 0.13796 ± 0.00004 cm−1. The rotational constants were used to provide values for the internuclear distances in these modecules.
