Reports on the Detection of Acetic Acid in the ISM
Acetic acide was detected in the 3 mm region toward the massive star-forming region Sgr B2(N-LMH) by
D. M. Mehringer, L. E. Snyder, Y. Miao, and F. J. Lovas,
Detection and Confirmation of Interstellar Acetic Acid
Astrophys. J. 480, L71–L74 (1997).
The oblate paired J = Kc = 8 – 7 A symmetry transition near 90.2 GHz was detected with BIMA, the 9 – 8 E symmetry transition near 100.9 GHz with OVRO.
The detection of still further transitions in Sgr B2(N-LMH) as well as in the additional hot core source W51e2 were reported by
A. Remijan, L. E. Snyder, S.-Y. Liu, D. Mehringer, and Y.-J. Kuan,
Acetic Acid in the Hot Cores of Sagitarrius B2(N) and W51
Astrophys. J. 576, 264–273 (2002).

Astron. Astrophys. 595, Art. No. A117 (2016).
The authors report the first unambiguous detection of acetic acid around a low-mass protostar. There were earlier tentative reports.
