U. Kretschmer, THE S-33 NUCLEAR-QUADRUPOLE HYPERFINE COUPLING IN THE ROTATIONAL SPECTRUM OF S-33 DIMETHYLSULFOXIDE, Zeitschrift fur Naturforschung. A, A journal of physical sciences, 50(7), 1995, pp. 666-668
The rotational spectrum of the S-33 dimethylsulfoxide in natural isoto
pic abundance has been studied using molecular beam Fourier transform
microwave spectroscopy. Rotational and quadrupole coupling constants c
ould be extracted from the spectra. They were found to be A = 7017.545
6(16) MHz, B = 6894.5117(17) MHz, C = 4218.14115(84) MKz, chi(aa) - 15
.720(18) MHz, chi(bb)= - 17.045(23), and X(cc) = 32.765(25) MHz.
