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 (68–116 GHz) in the 3 mm segment of a broadband survey of Sgr B2(N). Thirty very favorable rotational lines (Ka = 0 and Ka = 1 only; Eu < 60 K) originating in five consecutive transitions (J = 8 → ?> 7, 9 → ?> 8, 10 → ?> 9, 11 → ?> 10, and 12 → ?> 11) in both the A and E internal rotation species are present… 

A Comprehensive Spectral Rotational Analysis of the Interstellar Methyl Isocyanate CH3NCO

Methyl isocyanate (CH3NCO) is a recently identified interstellar molecule giving rise to many detected lines. Interestingly, its delayed identification was due not to weak lines but to a very complex

A rigorous detection of interstellar CH3NCO: An important missing species in astrochemical networks.

The recent analysis of the composition of the frozen surface of comet 67P/Churyumov-Gerasimenko has revealed a significant number of complex organic molecules. Methyl isocyanate (CH3NCO) is one of

The millimeter wave spectrum of methyl cyanate: a laboratory study and astronomical search in space.

The aim of this work is to fulfill the first requirement for methyl cyanate unequivocal identification in space, i.e. the availability of transition frequencies with high accuracy, and reproduce the spectrum close to the experimental uncertainty.

Laboratory study of methyl isocyanate ices under astrophysical conditions.

In this work, infrared spectra of solid CH3NCO have been obtained at temperatures of relevance for astronomical environments and the absence of new spectral features indicates that methyl isocyanate and water do not react appreciably at 20 K, but form a stable mixture.

The ALMA-PILS survey: detection of CH3NCO towards the low-mass protostar IRAS 16293−2422 and laboratory constraints on its formation

Methyl isocyanate (CH3NCO) belongs to a select group of interstellar molecules considered to be relevant precursors in the formation of larger organic compounds, including those with peptide bonds.

Abstract Methyl isocyanate (CH3NCO) belongs to a select group of peptide-like prebiotic molecules. In this paper we present its first detection toward the solar type low-mass protostar IRAS16293-2422

ALMA Observations of the Spatial Distribution of Three C2H4O2 Isomers toward Sgr B2(N)

The isomers have been previously investigated primarily via disparate sets of observations involving single-dish and array measurements. The only attempt at using a uniform set of observations was

Rotational spectrum of methoxyamine up to 480 GHz: a laboratory study and astronomical search.

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.

First detection of C2H5NCO in the ISM and search of other isocyanates towards the G+0.693-0.027 molecular cloud

Context. Little is known about the chemistry of isocyanates (compounds with the functional group R-N=C=O) in the interstellar medium (ISM), as only four of them have been detected so far: isocyanate
