qct calculations were performed to study the behavior of energized nh2oh formed by association collision of nh2 radical with oh radical. a potential energy surface that describes the behavior of the title reaction has been constructed by interpolation of ab initio data. h2o, hon, hno, nh3, o, h2no, cis or trans-honh, and h products and two vibrationally energized nh2oh and nh3o adducts were obs...

The reaction of atomic hydrogen with isocyanic acid (HNCO) to produce the amidogen radical (NHZ) and carbon monoxide, (W)) H + HNCO NH2 + CO has been studied in shock-heated mixtures of HNCO dilute in argon. Time-histories of the ground-state NHZ radical were measured behind reflected shock waves using cw, narrowlinewidth laser absorption at 597 nm, and HNCO time-histories were measured using i...

QCT calculations were performed to study the behavior of energized NH2OH formed by association collision of NH2 radical with OH radical. A potential energy surface that describes the behavior of the title reaction has been constructed by interpolation of ab initio data. H2O, HON, HNO, NH3, O, H2NO, cis or trans-HONH, and H products and two vibrationally energized NH2OH and NH3O adducts were obs...

The gas-phase reaction of nitric acid with the amidogen radical under atmospheric conditions has been investigated using quantum mechanical (QCISD and CCSD(T)) and DFT (B3LYP, BH&HLYP, M05, M05-2X, and M06-2X) calculations with the 6-311+G(2df,2p), aug-cc-pVTZ, aug-cc-pVQZ and extrapolation to the CBS basis sets. The reaction begins with the barrierless formation of a hydrogen-bonded complex, w...

We present quantum close-coupling calculations for the rotational excitation of the interstellar amidogen radical NH2 due to collisions with H2 molecules. The calculations are based on a recent, high-accuracy full-dimensional NH4 potential energy surface adapted for rigid-rotor scattering calculations. The collisional cross section calculations are performed for all transitions among the first ...

We present spectroscopy of the coma center comet C/2020 F3 (NEOWISE), carried out at end July 2020 with \'Echelle spectrograph FLECHAS University Observatory Jena. The was observed in 5 nights and many prominent emission features were detected between 4685\r{A} 7376\r{A}. Beside C$_2$ Swan bands also several amidogen radical, as well two forbidden lines oxygen identified spectra all observing e...
