A theoretical study of the rotational distribution of no resulting from dissociation of HNO

Abstract

Nascent NO (X2ΠΩ=1/2, 3/2, v=0) rotational distributions following the unimolecular dissociation of HNO at 5 and 300 K have been calculated at excess energies from 5 to 500 cm−1, using the statistical adiabatic channel model on anab initio potential energy surface. The influence of the tunneling effect through the adiabatic channel barriers on the average rotational energies is investigated.
