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 ofExpand
We report the first spectroscopic detection of ethyl cyanide (C2H5CN) in Titan’s atmosphere, obtained using spectrally and spatially resolved observations of multiple emission lines with the AtacamaExpand
Astronomical searches for nitrogen heterocycles
We have conducted extensive astronomical searches for the N-bearing ring molecules pyridine, quinoline and isoquinoline towards the circumstellar envelopes of carbon-rich stars, and for interstellarExpand
Formation and photostability of N-heterocycles in space. I. The effect of nitrogen on the photostability of small aromatic molecules
Nitrogen-containing cyclic organic molecules (N-heterocycles) play important roles in terrestrial biology, for exam- ple as the nucleobases in genetic material. It has previously been shown thatExpand
Structures of Cage, Prism, and Book Isomers of Water Hexamer from Broadband Rotational Spectroscopy
It is reported that broadband rotational spectroscopy in a pulsed supersonic expansion unambiguously identifies all three isomers of the water hexamer; their oxygen framework structures are determined by means of oxygen-18–substituted water (H218O). Expand
A search for interstellar pyrimidine
We have searched three hot molecular cores for submillimetre emission from the nucleic acid building block pyrimidine. We obtain upper limits to the total pyrimidine (beam-averaged) column densitiesExpand
Electric dipole moments of acrylonitrile and of propionitrile measured in supersonic expansion
Abstract New determinations of the ground-state electric dipole moments of acrylonitrile and propionitrile have been made from Stark effect measurements at conditions of supersonic expansion. TheExpand
ALMA detection and astrobiological potential of vinyl cyanide on Titan
The first spectroscopic detection of vinyl cyanide in Titan’s atmosphere is reported using archival data from the Atacama Large Millimeter/submillimeter Array (ALMA), collected from February to May 2014. Expand
Deep K-Band Observations of TMC-1 with the Green Bank Telescope: Detection of HC7O, Nondetection of HC11N, and a Search for New Organic Molecules
The 100 m Robert C. Byrd Green Bank Telescope K-band (KFPA) receiver was used to perform a high-sensitivity search for rotational emission lines from complex organic molecules in the coldExpand
