Absorption as well as emission lines were detected with the 100 m GBT dish between 18 and 26 GHz. This indicates that the molecules reside in the colder and less dense envelope of Sgr B2(N). While the detection of propanal appears to be secure, only two propenal lines have been detected thus far. Therefore, the detection of propenal should be viewed with some caution.However, | Absorption as well as emission lines were detected with the 100 m GBT dish between 18 and 26 GHz.

This report is the first one on the detection of warm (~125 K) propanal in the ISM as well as on the detection of propanal around a low-mass protostar. The Protostellar Interferometric Line Survey (PILS) was carried out with ALMA in its Band 7 (329 – 363 GHz). A total of 44 lines were assigned to propanal.\\ | This report is the first one on the detection of warm (~125 K) propanal in the ISM as well as on the detection of propanal around a low-mass protostar.
