✦ Synopsis

The first observation of the far-infrared laser magnetic resonance spectrum of the (\mathrm{HS}{\mathbf{2}}) radical in its ground ({ }^{2} A) " state is reported. The radical was produced in the gas-phase reaction between fluorine atoms and hydrogen sulfide. (\mathrm{H}{2} \mathrm{~S}). Spectra associated with several different rotational transitions (with values of (N) up to 30 and (K_{a}) up to 4 ) have been identified and analyzed to give an improved set of molecular parameters. In particular, the value for the centrifugal distortion constant (\Delta_{K}) of 24.339 (10) MHz is significantly different from the value assumed by (S). Yamamoto and S. Saito (Can. J. Phys. 72, 954 (1994)) in their earlier millimeter-wave study. Zeeman parameters have also been determined. (c) 1995 Academic Press. Inc.
