Notes

Abstract: The H+NH₃ reaction has been investigated using the high-temperature photochemistry (HTP) technique. H(1²S) atoms were generated by flash photolysis of NH₃ and monitored by time-resolved atomic resonance fluorescence with pulse counting. The rate coefficient for 660 ≤ T ≤ 1140 K is given by k (T) = (5.7 ± 2.8) x 10⁻¹⁰ exp[(- 8650 ± 410) K/T] cm³ molecule⁻¹ s⁻¹, where the uncertainties represent one standard deviation based on a propagation of error treatment including systematic errors. The Arrhenius plot reveals curvature between 500 and 660 K which follows the results of quantum mechanical tunneling calculations based on transitions state theory and an Eckart potential.
