In addition, two valence states labeled as the B̃‘ state (38623 cm -1) and C̃ state (56219−61278 cm -1) were also observed. The F̃ state might be a 4p Rydberg state of another hybrid symmetry with the quantum defect δ = 1.50. Incompletely rotational analysis revealed that the F̃ electronic state with ν 0 - 0 = 63812 cm -1, ω 1‘(a 1 sym str) = 966(6) cm -1, and ω 2‘(a 1, bend) = 417(23) cm -1 merges with the vibrational progression of the Ẽ (4p) state.

A second Rydberg series Ẽ (4p) with quantum defect δ = 1.61 is characterized with the spectroscopic values ν 0 - 0 = 62025 cm -1, ω 1‘(a 1 sym str) = 941(27) cm -1, and ω 2‘(a 1, bend) = 413(12) cm -1. Vibrational analyses of these Rydberg states showed that in the B̃ 1B 1(4s) state ω 1‘(a 1 sym str) = 981(23) cm -1 and in the J̃ 1B 1(5s) state ω 1‘(a 1 sym str) = 942(3) cm -1.
One series with quantum defect δ = 1.961(6) is comprised of the B̃ 1B 1(4s) and J̃ 1B 1(5s) Rydberg states which have origins at ν 0 - 0 = 5441 cm -1, respectively. Eight electronic band systems have been observed in this range. The (2+1) REMPI spectra of the SF 2 radicals were investigated between 245 and 365 nm (54945−81630 cm -1 ). A pulsed dc electric discharge in a pulsed supersonic beam has been used as an efficient source of producing radicals.
