Unimolecular and bimolecular calculations for HN2.

Using a recently reported double many-body expansion potential energy surface, quasi-classical, statistical mechanics, and quantum resonance calculations have been performed for the HN 2 system by focusing on the determination of bimolecular (N + NH and H + N 2 ) and unimolecular (decomposition of HN 2 ) rate constants as well as the relevant equilibrium constants.
