Vacuum ultraviolet photoelectron spectroscopic study of the NH2O and HNO molecules

Abstract

UV photoelectron spectra have been recorded for the F + NH2OH reaction at different reaction times. At short reaction times three bands associated with NH2O were observed, whereas at longer reaction times one band associated with NHO was seen.

The NH2O bands were assigned with the aid of ab initio molecular orbital calculations which used an essentially planar equilibrium geometry for the neutral ground state. The HNO band showed resolved vibrational structure which was analysed in terms of excitation of the N—O stretching and HNO deformation modes in HNO+(X 2A′). The first adiabatic and vertical ionization energies of HNO(X 1A′) were measured as 10.18 ± 0.01 and 10.56 ± 0.01 eV, respectively. Assignment of the vibrational structure was confirmed by recording the first photoelectron band of DNO, prepared from the F + ND2OD reaction.
