Direct dynamic study on the hydrogen abstraction reaction of H2CO with NCO
A direct ab initio dynamics method is used to investigate the hydrogen‐ion reaction of H2CO with NCO. The potential energy surface information is obtained at the MP2/6‐311G(d,p) level. More accurate single‐point energy is refined at the G3(MP2)//MP2/6‐311G(d,p) level. Furthermore, the rate constants...

description | A direct ab initio dynamics method is used to investigate the hydrogen‐ion reaction of H2CO with NCO. The potential energy surface information is obtained at the MP2/6‐311G(d,p) level. More accurate single‐point energy is refined at the G3(MP2)//MP2/6‐311G(d,p) level. Furthermore, the rate constants of reaction H2CO + NCO are evaluated by using the canonical variational transition state theory with small‐curvature tunneling contributions over a wide temperature range of 200–2000 K. The calculated reaction enthalpy and rate constants are in good agreement with the available experimental values. © 2009 Wiley Periodicals, Inc. Int J Chem Kinet 41: 394–400, 2009 |
