The chemiluminiscent reaction following the ultraviolet (266 nm) photolysis of HN, has been studied. A dispersed emission spectrum was recorded, which is, to the best of our knowledge, the fast direct identification of the origin of the chemiluminescence. The emissive species was assigned to vibroni

✦ Synopsis
The reaction between hydrogen atoms and hydrogen azide has been studied by the discharge flow method. Emissions from NH$AIL NH('Y and NH?fl) uere observed.
The NH,('AI) radical was highly excited in its ribrational states.
Dependence of the emission intensity on reactant concentrations was examined for both NH,('A,)
and NH(%) emission_ The results suggest that the NHJ'A,) is formed directly by reaction between H and HN,_ The eleclronically -cited NH('TI is probably produced by the reaction H+N,.
