HIGH RESOLUTION RAMAN SPECTROSCOPY OF GASES: XIV. ROTATIONAL SPECTRA OF C2H6, C2D6, C2H3D3 AND STRUCTURE OF THE ETHANE MOLECULE
Keyword(s):
An analysis of the rotational Raman spectra of three isotopic species of ethane has given the following values for the rotational constants:[Formula: see text]From these values alone it is found that r0(C—C) = 1.5376 ± 0.003 Å, and when these are combined with, already available values of Ia (the moment of inertia about the symmetric top axis), the CH3 parameters are determined to be r0(C—H) = 1.106 ± 0.006 Å and [Formula: see text].
