CH2（^3B1）与NO反应的势能面和速率常数的理论计算

摘要

The geometries of the reactants and product for the titled reaction are optimized at CAS(3,3)+1+2/cc-pvDZ level. The energetics of some crucial points along the minimum energy path are refined by CAS(3,3)+1+2/cc-pvTZ method. Based on RRKM theory, the rate constants for the titled reaction are calculated with the geometries and frequencies of CAS(3,3)+1+2/cc-pvDZ. The obtained values are in good agreement with the experimental ones.
