N2O and Other Nitrogen i Species

N2O and Other Nitrogen i) Species. The results of accurate configuration interaction calculations on the excited states of N2O have been used to provide accurate assignments of the observed excitation features. Current assignments of the N2O spectra have been compared, and results for the higher-lying valence states presented. This study also provides a comparison of the Hartree-Fock, INDO, and configuration interaction methods.  

Vacuum-u.v. photolysis of N2O isolated in Ar matrixes at 4 K gives direct luminescent evidence for the photodissociative production of both 0( S) and N( D) atoms. The matrix results have been compared to relative atomic quantum yields measured in the gas phase.  

SCF calculations have been carried out on the molecule HNO ( nitrosyl hydride ) and its isomer HON ( nitrogen hydroxide ). The system is found to have a low-lying triplet state, which is expected to aid in the dimerization to hyponitrous acid, H2O2N2. 

The steady-state concentration of NO obtained from air in a glow discharge at 1550—2000 K varies only with the gas temperature and is independent of gas pressure and density. The kinetics of NO decomposition in a barrier (silent) discharge have been studied. Under the experimental conditions employed, NO decomposes by a fast first-order reaction with an activation energy of 

The reaction of nitric oxide with hydrogen at 673 K is first-order in H2 and independent of NO pressure. The reaction proceeds by means of a free-radical chain mechanism
