The triplet (g) over tilde Rydberg state of SO2 with an origin at 78 245.8 cm(-1), 526 cm(-1) below the previously detected singlet (G) over tilde state origin, has been observed in a two-color resonantly enhanced multiphoton ionization experiment. The bending vibrational levels (v=0-5 with intervals of 400 +/- 10 cm(-1)) has been identified and reported. Based on the symmetry, bending frequencies, quantum defects, and term values, this (G) over tilde state singlet-triplet pair was assigned to the sulfur 4p state belonging to the series converging to the SO2+ (X) over tilde (2)A(1) state. The same procedure also allows the reassignment of the Rydberg state previously observed in the 111.5-115 nm region to the sulfur 4p orbital (converging to the SO2+ (A) over tilde (2)A(2) state) and the one in the 106.3-110.4 nm region to the 5p orbital (converging to the SO2+ (X) over tilde (2)A(1) state). The spectral patterns also indicate that the (G) over tilde states have a detectable increase in the dissociation rate above the v(2)=2 level. The triplet state near the 193 nm region is dissociative with a homogeneous width of similar to 13 cm(-1).
