✦ Synopsis

The reaction between H2S and C1F was precluded and H2S... C1F isolated by a coaxial supersonic expansion of the gaseous components into the Fabry-P6rot cavity of a pulsed-nozzle, Fourier-transform microwave spectrometer. The ground-state rotational spectra of seven isotopomers of HzS... C1F were analysed and gave in each case the spectroscopic 1 constants 2(B o + Co), Dj, Xaa (C1) and Mbb (CI). Interpretation of these constants revealed the complex to have a geometry of C s symmetry with the S... CI-F nuclei collinear in the order shown, with the angle 180 ° -~b = 84.2(4) ° between the C 2 axis of H2S and the S... CI-F axis, and with r(S... C1) = 2.857(3) ,~.
