Experimental and Theoretical Investigation of the Reaction of NH₂ with NO at Very Low Temperatures.

ABSTRACT: The first experimental study of the low-temperature kinetics of the gas-phase reaction between NH₂ and NO has been performed. A pulsed laser photolysis-laser-induced fluorescence technique was used to create and monitor the temporal decay of NH₂ in the presence of NO. Measurements were carried out over the temperature range of 24-106 K, with the low temperatures achieved using a pulsed Laval nozzle expansion. The negative temperature dependence of the reaction rate coefficient observed at higher temperatures in the literature continues at these lower temperatures, with the rate coefficient reaching 3.5 × 10^-10 cm³ molecule^-1 s^-1 at T = 26 K. Ab initio calculations of the potential energy surface were combined with rat
