The ³³S Nuclear Quadrupole Coupling in the Rotational Spectrum of anti-2,3-Dimethylthiirane

Abstract

The rotational spectrum of 33 S a/j//'-2,3-dimethylthiirane with its 33 S nuclear quadrupole coupling hyperfine structure in the range 7.6 to to 21.5 GHz and its analysis is reported. The rotational constants are A = 5331.1401 (5), B = 3506.3963(10), and C = 2356.9273(2) MHz. The 33 S quadrupole coupling constants are \aa = 8.3871(93), Xbb = -32.3291(174), and Xcc = 23.9420(174) MHz.
