Abstract
The chemiluminescence spectrum of product OH(A(2)Sigma) in a crossed b eam reaction of the hot H atom with N2O was observed for the first tim e. The nascent internal-state distribution of OH(A(2)Sigma) was identi fied by spectral simulation. The rotational distribution was found to be characterized by a Boltzmann temperature of 750 +/- 100 K, and the vibrational distribution is non-Boltzmann with the populations of nu = 0, 1, and 2 being 1:0.75:0.15, respectively. These results indicate t hat the product rotation is poorly excited while vibration is highly e xcited to the contrary.
