✦ Synopsis

The rotationally resolved emission spectra of NH(c 'n) was observed in the vacuum UV photolysis of ammonia by Ar, Kr and H resonance lines. Hot rotational distribution was reconfirmed for photolysis by either the Kr or the H line, while, in the case of Ar, NH(c 'II) was found to be cold. From the maximum rotational line observed in the 123.6 nm photolysis, the heat of formation of NH is determined to be 90.2-91.3 kcalimol.

Using resoaance fluorescence the kinetics of NH (X 3~-) was studied in the pulsed vacuum UV photolysis of mixtures of NH3 and NO. The rate constant of the reaction NH + NO was determined to be (4.7 f 1.2) x lO\_" cm3 m01ecuIe-~ ssl. in the course of an investigation of the kinetics of imino radicals

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
