Abstract

We have measured the 3_1,3-2_0,2 transition of SO₂ in W49, W51, OriA and Sgr B2, and found SO₂ emission upper limits in a further seven sources. The total number of SO2 molecules in individual clouds is found to range from ~2×10⁵¹ to ~10⁵³, implying a relative abundance X(SO₂) ~ 10^-6 in OriA, and lower limits varying from X(SO₂) ~ 10^-9 to ~10^-8 in the remaining sources. These results are briefly discussed within the context of current models of interstellar cloud chemistry.
