Abstract:
The net probabilities of reactions (1) and (2) have been determined as a function of the initial
kinetic energy of H* by analysis of the products of photolysis, at various wavelengths, of Hl mixed
with N2O.
H* + N2O->N2 + OH
H* + N2O->NO + NH
(1)
(2)
Reaction (1) is predominant at all energies studied. The results have been used to calculate a crude
excitation function for reaction (1), which has a maximum cross section of about 6x 10“ 3 nm2.
By using the excitation function to calculate rate coefficients, which are in good agreement with
experimental values, the hot atom results arc shown to be consistent with measurements of the rate of
(1) in thermal systems at high temperatures.
