Over 800 lines in OMC-1 and over 700 in Sgr B2 were observed in the NRAO 3-mm survey. Detailed LTE analysis of 33 species has been performed using numbers of transitions in the range 4-98. Limitations of the LTE optically thin approach are emphasized, in particular its failure to account for the anomalously strong emission from intrisically weak transitions in all the most complex species including CH3OHCO, (CH3)2O, CH3CHO, EtOH, NH2CHO, CH2CHCN, and EtCN. A detailed radiative-transfer analysis… Expand
A Three-Position Spectral Line Survey of Sagittarius B2 between 218 and 263 GHZ. II. Data Analysis
We present an analysis of the data from our Swedish-ESO Submillimetre Telescope molecular line survey in the 1.3 mm band of the N, M, and NW positions in the Sgr B2 molecular cloud. The lineExpand
A sensitive broadband molecular line survey of the Sagittarius B2(N) star-forming region has been obtained with the Heterodyne Instrument for the Far-Infrared (HIFI) instrument on the Herschel SpaceExpand
A Molecular Line Survey of W3(OH) and W3 IRS 5 from 84.7 to 115.6 GHz: Observational Data and Analyses
We have carried out observations toward the W3 complex and G34.3+0.15 using the TRAO 14 m radio telescope to examine in detail the chemical variations occurring while molecular clouds evolve from theExpand
A line survey of Orion KL from 325 to 360 GHz.
A high-sensitivity spectral line survey of the high-mass star-forming region Orion KL in the 325-360 GHz frequency band was conducted at the Caltech Submillimeter Observatory on Mauna Kea, Hawaii, and was able to strengthen evidence for the identification of ethanol in Orion and found the first nitrogen sulfide line in this source.

HCl absorption toward Sagittarius B2.
Comparison of this result to chemical models indicates that the depletion factor of gas-phase chlorine is between 50-180 in the molecular envelope surrounding the SgrB2(N) and (M) dust cores. Expand
Complex organic molecules in the interstellar medium: IRAM 30 m line survey of Sagittarius B2(N) and (M)
The discovery of amino acids in meteorites and the detection of glycine in samples returned from a comet to Earth suggest that the interstellar chemistry is capable of producing such complex organicExpand
A spectral line survey of Orion KL in the bands 486-492 and 541-577 GHz with the Odin satellite II. Data analysis
Aims. We investigate the physical and chemical conditions in a typical star forming region, including an unbiased search for new molecules in a spectral region previously unobserved. Methods. Due toExpand
A three-position spectral line survey of Sagittarius B2 between 218 and 263 GHz. I. The observational data
We have surveyed the frequency band 218.30-263.55 GHz toward the core positions N and M and the quiescent cloud position NW in the Sgr B2 molecular cloud using the Swedish-ESO SubmillimetreExpand
44 GHz Methanol Masers and Quasi-Thermal Emission in Sagittarius B2
The Very Large Array has been used to obtain ~3'' resolution observations on the 44 GHz 70 → 61A+ transition of CH3OH (methanol) in the Sgr B2 massive star-forming complex. A total of 18 compactExpand
A Spectral Line Survey from 138.3 to 150.7 GHz toward Orion-KL
We present the results of a spectral line survey from 138.3 to 150.7 GHz toward Orion-KL. The observations were made using the 14 m radio telescope of Taeduk Radio Astronomy Observatory. TypicalExpand
