HS radicals have been generated by the photodissociation of H2S at 193 nm and their disappearance monitored by LIF. The reaction of HS with NO, like the analogous reaction of OH with NO, has been shown to involve a third body. The low pressure rate coefficients have been determined for He, Ar, and N2. The values are 2.1, 2.2, and 2.4×10−31 cm6 molecule−2 s−1, respectively, with estimated uncertainties of ±10%. The high pressure limit is (2.8±1.0)×10−11 cm3 molecule−1 s−1. The reaction with NO2 (HS+NO2→HSO+NO) is second order with a rate coefficient of (3.5±0.4)×10−11 cm3 molecule−1 s−1. An upper limit for the rate coefficient with O2 has been estimated (4×10−17 cm3 molecule−1 s−1).

The microwave spectra of the HSO and DSO radicals in the ground state were observed in glow discharges in a mixture of H2S or D2S and O2. Both a-type and b-type transitions were assigned and analyzed. The hyperfine coupling constants of the hydrogen nucleus of HSO were determined for the first time. These constants resulted in a conclusion that the ground electronic state of HSO is 2A″. The rotational constants, centrifugal distortion constants, and spin–rotation coupling constants including their centrifugal distortion terms for both the species were also determined with good precision. The diagonal components of the magnetic hyperfine interaction for the deuterium nucleus of DSO were not obtained because most of the hyperfine splittings were not resolved or resolved partially. However, the off-diagonal component Tab was determined from an analysis of a local perturbation between the 312 J = 7/2 and 404 J = 7/2 levels connected by the εab+εba term.
