DISCOVERY OF FULMINIC ACID, HCNO, IN DARK CLOUDS [PDF]

The Astrophysical Journal, 2008
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 40-70.

Photoelectron spectroscopy and dissociative photoionization of fulminic acid, HCNO

The Journal of Chemical Physics, 2023
We report a joint experimental and computational study of the photoelectron spectroscopy and the dissociative photoionization of fulminic acid, HCNO. The molecule is of interest to astrochemistry and astrobiology as a potential precursor of prebiotic molecules. Synchrotron radiation was used as the photon source.

Rotation-Vibration Interaction in the Microwave Spectrum of Fulminic Acid, HCNO [PDF]

Zeitschrift für Naturforschung A, 1969
Abstract Rotational transitions in the microwave spectrum (20 - 46 GHz) of HCNO have been measured and assigned to seven excited vibrational states. The direct l-type doubling transitions of the II-component of the vibrational levels ν5 = 3 have been measured and analyzed, yielding the following values: q(0)

Rotational excitation of fulminic acid (HCNO) in collisions with molecular hydrogen

Physical Chemistry Chemical Physics
Fulminic acid is an isomer of isocyanic acid, which is widely distributed in the interstellar medium. We present a calculation of its interaction potential with a hydrogen molecule and calculate collisional excitation properties.

Analytical improvements and developments in stable isotope laboratories for HCNOS analyses

MethodsX
Analytical improvements and developments in stable isotope laboratories for HCNOS analysesThe analyses of the stable isotope compositions of light elements, such as hydrogen (H), carbon (C), nitrogen (N), oxygen (O), and sulphur (S), are now widely employed across various research areas, including agriculture, archology, biochemistry, biology ...
