✦ Synopsis

Laser-induced excitation spectra of the two bands a ˜3B 1 -X ˜1A 1 , 2 0 1 and 1 0 1 of 32 SO 2 and 34 SO 2 have been recorded in a supersonic jet at a resolution of 0.015 cm Ϫ1 . The rotational and electron-spin fine structure has been analyzed for both isotopic species. Analysis of the rotational and electron-spin fine structure yields precise values of the rotational constants A, B, and C and the spin constants ␣ and ␤ for both 32 SO 2 and 34 SO 2 in the states a ˜3B 1 ( 010) and ( 100). No interaction between these two vibrational states with any nearby triplet state is observed for rotational levels with J Յ 8 and K Յ 2.
