The infrared spectra of the van der Waals complex between CO and H2S were recently studied by Xia and McKellar. Following this investigation, we have measured rotational spectra of several isotopomers of CO–H2S using a cavity Fourier transform microwave spectrometer. Nuclear hyperfine structures due to the quadrupolar 33S and 17O nuclei were observed and analyzed. The resulting rotational and hyperfine constants were used to derive structural and dynamical information about the complex.
