Ten ΔJ= 1 rotational transitions for the SO2-H2S complex were observed in the 4-12 GHz frequency range using a pulsed-beam Fourier-transform microwave spectrometer. The complex is a near-prolate asymmetric top with 1 2(B + C) = 1649(6) MHz and B - C = 228(10) MHz. Some of the observed transitions show inversion or hindered internal rotation splittings. A tentative structure is a non-planar cyclic complex containing two hydrogen bonds from H2S to the oxygen atoms on SO2.
