The reaction between H2S and ClF was precluded and H2S...ClF isolated bya coaxial supersonic expansion of the gaseous components into the Fabry -Perot cavity of a pulsed-nozzle, Fourier-transform microwave spectrometer. The ground-state rotational spectra of seven isotopomers of H2S...ClF were analysed and gave in each case the spectroscopic constants 1/2(B(0)+C(0)), D(J), χ(aa) (Cl) and M(bb) (Cl). Interpretation of these constants revealed the complex to have a geometry of C(s) symmetry with the S...Cl-F nuclei collinear in the order shown, with the angle 180°-φ=84.2(4)° between the C(2) axis of H2S and the S...Cl-F axis, and with r(S...Cl)=2.857(3)?.
