In 2003, Kuan and coworkers reported the detection of interstellar glycine (NH2CH2COOH) based on observations of 27 lines in 19 different spectral bands in one or more of the sources Sgr B2(N-LMH), Orion KL, and W51 e1/e2. They supported their detection report with rotational temperature diagrams for all three sources. In this paper we present essential criteria that can be used in a straightforward analysis technique to confirm the identity of an interstellar asymmetric rotor such as glycine… Expand
About the detectability of glycine in the interstellar medium
Context. Glycine, the simplest of aminoacids, has been found in several carbonaceous meteorites. It remains unclear, however, wether glycine is formed in the interstellar medium (ISM) and thereforeExpand
HCOOCH3 as a probe of temperature and structure in Orion-KL
Context. The Orion Kleinmann-Low nebula (Orion-KL) is a complex region of star formation. Whereas its proximity allows studies on a scale of a few hundred AU, spectral confusion makes it difficult toExpand
Observational Results of a Multi-telescope Campaign in Search of Interstellar Urea [(NH2)2CO]
In this paper, we present the results of an observational search for gas phase urea [(NH_2)_2CO] observed toward the Sgr B2(N-LMH) region. We show data covering urea transitions from ~100 GHz to 250Expand
Interstellar glycolamide: A comprehensive rotational study and an astronomical search in Sgr B2(N).
TLDR
This work provides direct experimental frequencies of the ground vibrational state of glycolamide in the centimeter-, millimeter- and submillimeter-wavelength regions in order to enable its identification in the interstellar medium. Expand
A search for propylene oxide and glycine in Sagittarius B2 (LMH) and Orion
We have used the Mopra Telescope to search for glycine and the simple chiral molecule propylene oxide in the Sgr B2 (LMH) and Orion KL, in the 3-mm band. We have not detected either species, but haveExpand
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
LABORATORY DETECTION OF HOCN AND TENTATIVE IDENTIFICATION IN Sgr B2
The rotational spectrum of cyanic acid, HOCN, has been detected in the centimeter-wave band in a molecular beam by Fourier transform microwave spectroscopy and in the millimeter-wave band byExpand
INTERSTELLAR DETECTION OF METHYL ISOCYANATE CH3NCO IN Sgr B2(N): A LINK FROM MOLECULAR CLOUDS TO COMETS
A new interstellar molecule, CH3NCO (methyl isocyanate), has been detected using the 12 m telescope of the Arizona Radio Observatory (ARO). CH3NCO was identified in spectra covering 48 GHz (68–116Expand
Interstellar Carbodiimide (HNCNH): A New Astronomical Detection from the GBT PRIMOS Survey via Maser Emission Features
In this work, we identify carbodiimide (HNCNH), which is an isomer of the well-known interstellar species cyanamide (NH2CN), in weak maser emission, using data from the Green Bank Telescope PRIMOSExpand
Rotational spectrum of methoxyamine up to 480 GHz: a laboratory study and astronomical search.
TLDR
Methoxyamine is a potential interstellar amine that has been predicted by gas-grain chemical models for the formation of complex molecules and direct experimental frequencies of its ground-vibrational state in the millimeter- and submillimeter-wave regions are provided to achieve its detection in the interstellar medium.

Detection of interstellar ethylene oxide (c-C2H4O).
TLDR
It is suggested that grain chemistry might play an effective role in the production of c-C2H4O, which is a factor of more than 200 higher than the abundance for this molecule suggested by the "new standard" chemistry model of Lee, Bettens, & Herbst. Expand
