A pulsed dc discharge in a pulsed supersonic beam has been developed as an efficient source of producing free radicals. Spectra of the SF2 radical were observed between 272 and 294 nm by (2+1) resonance-enhanced multiphoton ionizition (REMPI) spectroscopy. Vibrational progressions associat-ed with 3d and 5s Rydberg states were assigned. The spectroscopic values ω1 (a1, symmetric stretch-ing), band origin T0 and quantum defect δ of these Rydberg states were reported.
