Detection of Interstellar Lines of Para-Formaldehyde and OCS and Searches for Other Molecular Lines at 73GHz
Abstract
The 1_{01}--0_{00} line of para-formaldehyde and J = 6 to 5 line of OCS were detected in Sgr B2. The formaldehyde line was also detected in Ori A (OH source). Antenna temperatures of these lines were 0.3 K, 0.25 K, and 0.5 K, respectively. Searches were made without success for these lines in W 51, Heiles cloud 4, and IRC +10216 and also for other lines of methylamine, HCCCN, and SO in all sources mentioned above.
