MICROWAVE SPECTROSCOPIC STUDY OF THE $CO-H_{2}S$ COMPLEX

$^{a}$C. Xia and A. R. W. McKellar, private communicationAuthor Institution: University of Alberta; Department of Chemistry, University of AlbertaThe infrared spectra of the van der Waals complex between $CO$ and $H_{2}S$ were recently studied by Xia and $McKellar.^{a}$ Following this investigation, we have measured rotational spectra of several isotopomers of $CO-H_{2}S$ using a cavity Fourier transform microwave spectrometer. Nuclear hyperfine structures due to the quadrupolar $^{33}S$ and $^{17}O$ nuclei were observed and analyzed. The resulting rotational and hyperfine constants were used to derive structural and dynamical information about the complex
