ab initio Investigation of the CH ( X2 ∏ ) + NNO Reaction
- Received Date: 2002-09-12
Abstract: There action mechanism CH(X2Π)+NNO is investigated at the level of G2(B3LYP/MP2/CC). The equilibrium geometries, harmonic frequencies and energy of various stationary points on the potential energy surfaces have been calculated in the lowest dublet states. It is found that there are two reaction mechanisms. The intermediate HC( N)NO is first formed through a composite process, and then it will dissociate to HCN+NO, which is one of the most primary reaction channels. HC inserts into the NO bond, and produces an activated intermediate HC(O)NN over a barrier of 38.9 k J/mol. Then, it is flowed by five product channels, and one among them is rather important, i.e. CO+HNN.
