Laboratory rotational spectroscopy of acrylamide and search for acrylamide and propionamide toward Sgr B2(N) with ALMA
L. Kolesniková, A. Belloche, J. Koucký +7
Numerous complex organic molecules have been detected in the universe among which amides are considered as models for species containing the peptide linkage. Acrylamide bears in it…
Millimetre-wave laboratory study of glycinamide and search for it with ALMA toward Sagittarius B2(N)
Z. Kisiel, L. Kolesniková, A. Belloche +9
Glycinamide is considered to be one of the possible precursors of the simplest amino acid glycine. Its only rotational spectrum reported so far has been in the cm-wave region. The…
Formation of complex organic molecules in hot molecular cores through nondiffusive grain-surface and ice-mantle chemistry
Robin T. Garrod, Mihwa Jin, Kayla A. Matis +3
A new, more comprehensive model of gas-grain chemistry in hot molecular cores is presented, in which nondiffusive reaction processes on dust-grain surfaces and in ice mantles are i…
Protostellar Interferometric Line Survey of the Cygnus X region (PILS-Cygnus) -- First results: observations of CygX-N30
S. J. van der Walt, L. E. Kristensen, J. K. Jørgensen +5
(Abridged) Complex organic molecules (COMs) are commonly detected in and near star-forming regions. However, the dominant process in the release of these COMs from the icy grains -…
Chemical Kinetics Simulations of Ice Chemistry on Porous Versus Non-Porous Dust Grains
Drew A. Christianson, Robin T. Garrod
The degree of porosity in interstellar dust-grain material is poorly defined, although recent work has suggested that the grains could be highly porous. Aside from influencing the…
Toward a global model of the interactions in low-lying states of methyl cyanide: rotational and rovibrational spectroscopy of the state and tentative interstellar detection of the state in Sgr B2(N)
Holger S. P. Müller, Arnaud Belloche, Frank Lewen +4
New and existing rotational spectra of methyl cyanide were analyzed to extend the global model of low-lying vibrational states and their interactions to at 920 cm. T…
