reported on the
Radio Detection of Interstellar Sulfur Dioxide
Astrophys. J. 198, L81–L84 (1975).
The NRAO 11 m dish was used to detect three transition in the Orion Molecular Cloud-1: 81,7 – 80,8 (83688.093 MHz); 83,5 – 92,8 (86639.088 MHz); and 73,5 – 82,6 (97702.334 MHz).

Observations of Sulfur Dioxide in the Kleinmann-Low Nebula
Astrophys. J. 284, 161 – 171 (1983).
The OSO 20 m dish was used to detect several transitions of SO2 along with three of 34SO2.
