摘要: Abstract Potential energy surface of the reaction NH 2 +NO → H +N O has been studied at several high levels ab initio molecular orbital theory. The pathway involves initially formation without a barrier twisted non-planar H N–NO nitrosamine intermediate, and C s symmetry transition state, followed by dihydrogen elimination to form products. path bifurcates before state. At MP4(SDTQ)/6-311G(2d,p)//CASSCF/6-31G(d,p) level theory, for this is found be +33.7 kcal/mol.
