The Study on the Atom and Molecule-Ion Reaction N'+NH⁺(0,0)→N+N'H⁺(υ',j')

The analytical potentinl energy function of (NNH)^＋ has been derived using the many-body terms expansion and the atom and molecule-ion reaction N'+NH^＋(0,0)→N+N'H^＋ (u',j') has been investigated using the quasiclassical trajectory method. The reactive cross sections were evaluated and the results showed that this reaction is a direct exchange reaction with a threshold energy 48hcal/mol. Based on the potential surface analysis,the reaction mechanism has been explained successfully.
