✦ Synopsis

he photodetachment of electrons from gaseous SH-ions has beerr studied in an ion cyclotron resonance mass spectrometer using a flashlamp-pumped organic dye laser as a light source. qe onset of the photodehchment process at 538.7 f 0.3 nm (2.3016 * 0.0013 eV, 18563 r lb c-m-l) agrees well with that obtained in an eariier study. Coarse structure in the photodetachment curve with a spacing of 11.8 nm (0.052 eV, 422 cm-') has been identified with spin-orbit coupling in th" SH. radical. Finer structure, with a spacing of ca. 2.5 nm (0.011 eV, 89 cm-'). has also been observed in the curve, but remains untsplained.
