We report on the first detection in space of fulminic acid, HCNO. This isomer of HNCO has been observed in three starless cores, B1, L1544, and L183, and in the low-mass star-forming region L1527 with a measured abundance ratio of HNCO/HCNO between 40 and 70. However, HCNO was not detected toward the direction of the cyanopolyyne peak of TMC-1 or toward the Orion Hot Core region. The derived HNCO/HCNO abundance ratio in these cases is greater than 350 and 1000 in TMC-1 and Orion, respectively… 

The puzzling behavior of HNCO isomers in molecular clouds

Context. Isocyanic acid (HNCO) has been observed in different physical environments in the interstellar medium (ISM) and in external galaxies. HNCO has several metastable isomers with a ground

DISCOVERY OF THE METHOXY RADICAL, CH3O, TOWARD B1: DUST GRAIN AND GAS-PHASE CHEMISTRY IN COLD DARK CLOUDS

We report on the discovery of the methoxy radical (CH3O) toward the cold and dense core B1-b based on the observation, with the IRAM 30 m radio telescope, of several lines at 3 and 2 mm wavelengths.

Shedding light on the formation of the pre-biotic molecule formamide with ASAI

Formamide (NH2CHO) has been proposed as a pre-biotic precursor with a key role in the emergence of life on Earth. While this molecule has been observed in space, most of its detections correspond to

GAS-GRAIN MODELING OF ISOCYANIC ACID (HNCO), CYANIC ACID (HOCN), FULMINIC ACID (HCNO), AND ISOFULMINIC ACID (HONC) IN ASSORTED INTERSTELLAR ENVIRONMENTS

Isocyanic acid (HNCO) is a well-known interstellar molecule. Evidence also exists for the presence of two of its metastable isomers in the interstellar medium: HCNO (fulminic acid) and HOCN (cyanic

Discovery of the elusive radical NCO and confirmation of H2NCO+ in space.

The first detection in space of NCO towards the dense core L483 is reported and the identification of the ion H2NCO+, definitively confirming its presence in space, and observations of HNCO, HOCN, and HCNO in the same source are reported.

A SEARCH FOR INTERSTELLAR CARBON-CHAIN ALCOHOL HC4OH IN STAR-FORMING REGION L1527 AND DARK CLOUD TMC-1

We report a sensitive search for the rotational transitions of the carbon-chain alcohol HC4OH in the frequency range 21.2–46.7 GHz in the star-forming region L1527 and the dark cloud TMC-1. The

Modelling the abundance structure of isocyanic acid (HNCO) towards the low-mass solar type protostar IRAS 16293–2422

Isocyanic acid (HNCO), the most stable of the simplest molecules containing the four main elements essential for organic chemistry, has been observed in several astrophysical environments such as

MECHANISM AND KINETICS FOR THE REACTION OF FULMINIC ACID, HCNO, WITH AN AMINO RADICAL, NH2

The reaction of fulminic acid, HCNO, with NH2 radicals was studied using quantum chemical and theoretical kinetic methodologies. B3LYP/6-311++G(3df,2p) calculations combined with CCSD(T) energy

Ionization fraction and the enhanced sulfur chemistry in Barnard 1.

Barnard B1b presents similar depletions of C and O than those measured in pre-stellar cores, and it is proposed that it is the consequence of the initial conditions and a rapid collapse that permits to maintain most S- and N-bearing species in gas phase to great optical depths.
