COVID Resources. Reliable information about the coronavirus (COVID) is available from the World Health Organization (current situation, international travel).Numerous and frequently-updated resource results are available from this ’s WebJunction has pulled together information and resources to assist library staff as they consider how to handle coronavirus.

We report a search in cold, quiescent and in hot core type interstellar molecular clouds for the small cyclic molecule oxiranecarbonitrile (C3H3NO), which has been suggested as a precursor of important prebiotic molecules. We have determined upper limits to the column density and fractional abundance for the observed sources and find that, typically, the fractional abundance by number relative Cited by: 9.

Ethylene oxide (IUPAC name oxirane) is one of only a handful of cyclic molecules that have been found in the interstellar medium, all of which except benzene involve three-membered rings. It was detected by radio astronomers by observing pure rotational transitions at millimeter wavelengths in the Galactic Center hot core SgrB2(N).

Irvine's research works with 6, citations and 1, reads, including: The Redshift Search Receiver 3 mm Wavelength Spectra of 10 Galaxies. An aspect of these studies is the search for and identification of new interstellar molecules. My colleagues and I have played a role in the discovery of some 13 such new molecular species, involving collaborations with astronomers at Nobeyama Radio Observatory in Japan and the Onsala Space Observatory in Sweden.

We report a search in cold, quiescent and in 'hot core' type interstellar molecular clouds for the small cyclic molecule oxiranecarbonitrile (C3H3NO), which has been suggested as a precursor of important prebiotic molecules.

Irvine, M Ohishi, G Arrhenius, S Pitsch, A Bauder, F Muller, and A Eschenmoser A search for low surface brightness galaxies in the near-infrared - II.

A search has been performed for interstellar CH3D via its J(K) = 1(0) - 0(0) transition at GHz and its J(K) = 2(0) - l(0) and J(K) = 2(1) - 1(1) lines at GHz using the NRAO 12 m and CSO 10 m telescopes towards Orion-KL.

This search was done in conjunction with laboratory measurements of all three transitions of CH3D using mm/sub-mm. Interstellar Molecules. ERIC Educational Resources Information Center. Solomon, Philip M. Radioastronomy reveals that clouds between the stars, once believed to consis. History Although its rotational spectrum has been studied since the s, and modeled explicitly for a search in the interstellar medium inaminoacetonitrile has only been detected recently in space in a large molecular cloud Sagittarius B2 (Sgr B2), at the center of the Galaxy (Belloche et al.

In view of the chemical attractiveness of the ocn scheme, a radiotelescope search of the interstellar medium for its microwave signature has been initiated; the early results of this investigation show that the abundance is below the detection limit of the technique so far used (Dickens et al.

); condensation of low vapor pressure products. With the Cologne group, Herbst analyzed the THz spectrum of the simple free radical methylene (CH2), which is likely to be abundant in an assortment of interstellar regions.

Herbst's program of modeling the gas-phase and grain-surface chemistry of interstellar clouds continues, with an emphasis on star formation regions.
