Abstract A 12-line EPR spectrum at a microwave frequency of 8.850 kMc/sec was observed in the field region from 7400 to 7700 G that is attributed to electric- dipole transitions between Zeeman levels of the J - 3/2 rotational state of gaseous SH(/sup 2/II/sub 3/2/. Average LAMBDA splittings and proton hyperfine splittings were 190 G and 5.4 G, respectively. The SH radicals were produced in the spectrometer cavity by adding H/sub 2/S at the cavity entrance to a stream of dischargedissociated H/sub 2/O vapor flowing through the cavity. When H/sub 2/S/ was added to a stream of dissociated D/sub 2/O, an additional spectrum attributed to SD(/sup 2/II/sub 3/2//, J =3/2) was observed. Another species in the gaseous systems gives rise to a third EPR spectrum that is believed to result from electricdipole transistors between Zeeman levels of different rotational states of SO(/sup 3/ SIGMA ).
