X-ray induced fragmentation of fulminic acid, HCNO
The Journal of Chemical Physics, 2023The fragmentation of fulminic acid, HCNO, after excitation and ionization of core electrons was investigated using Auger-electron–photoion coincidence spectroscopy. A considerable degree of site-selectivity is observed. Ionization of the carbon and oxygen 1s electron leads to around 70% CH+ + NO+, while ionization at the central N-atom produces only 37%

Kinetics of the O + HCNO Reaction
The Journal of Physical Chemistry A, 2007The kinetics of the O + HCNO reaction were investigated by a relative rate technique using infrared diode laser absorption spectroscopy. Laser photolysis (355 nm) of NO2 was used to produce O atoms, followed by O atom reactions with CS2, NO2, and HCNO, and infrared detection of OCS product from the O + CS2 reaction.

Kinetics of the CN + HCNO Reaction
The Journal of Physical Chemistry A, 2006The kinetics of the CN + HCNO reaction were studied using laser-induced fluorescence and infrared diode laser absorption spectroscopy. The total rate constant was measured to be k(T) = (3.95 +/- 0.53) x 10(-11) exp[(287.1 +/- 44.5)/T] cm3 molec(-1) s(-1), over the temperature range 298-388 K, with a value of k1 = (1.04 +/- 0.1) x 10(-10) cm3 molec(-1 ...

Kinetics of the OH + HCNO Reaction
The Journal of Physical Chemistry A, 2006The kinetics of the OH + HCNO reaction was studied. The total rate constant was measured by LIF detection of OH using two different OH precursors, both of which gave identical results. We obtain k = (2.69 +/- 0.41) x 10(-12) exp[(750.2 +/- 49.8)/T] cm(3) molecule(-1) s(-1) over the temperature range 298-386 K, with a value of k = (3.39 +/- 0.3) x 10 ...

Recalculation of stable isotope expressions for HCNOS: EasyIsoCalculator
Rapid Communications in Mass Spectrometry, 2020Rationale The stable HCNOS isotope compositions can be reported as (a) the isotope ratio of two stable isotopes ( R ); (b) the isotope delta value ( δ ); and (c) the atom fraction of the isotopes (

Kinetics of the NCO + HCNO Reaction
The Journal of Physical Chemistry A, 2006The kinetics of the NCO + HCNO reaction were studied using infrared diode laser absorption spectroscopy. The total rate constant was measured to be k(1) = (1.58 +/- 0.20) x 10(-11) cm(3) molecule(-1) s(-1) at 298 K. After detection of products and consideration of secondary chemistry (primarily O + HCNO and CN + HCNO), we conclude that NO + CO + HCN is

Journal of Molecular Spectroscopy, 1979
Abstract The semirigid bender Hamiltonian [Bunker and Landsberg, J. Mol. Spectrosc. , 67 , 374–385 (1977)] is used to fit the rotation-vibration energy level separations in the fulminic acid (HCNO) molecule. The allowance made in the model for the variation of the CH and CN bond lengths with the HCN bending angle proves to be very important, and as

Product Channels of the CN + HCNO Reaction
The Journal of Physical Chemistry A, 2012The kinetics of the reaction of CN radical with fulminic acid (HCNO) was studied by transient infrared absorption spectroscopy with the primary goal of resolving whether the dominant product channel is NO + HCCN (1a) or HCN + NCO (1b). HCN, HCCN, and NO reaction products were directly detected.
