Author(s):   Wang, S.K.; Zhang, Q.Z.; Gu, Y.S.
Title:   Theoretical study on the abstract reaction of O(3P) with CHFCl2
Journal:   Chem. Phys. Lett.
Volume:   373
Page(s):   33 - 38
Year:   2003
Reference type:   Journal article
Squib:   2003WAN/ZHA33-38

Reaction:   O(3P) + CHFCl2CF2Cl2 +
Reaction order:   2
Temperature:   200 - 3000 K
Rate expression:   1.6x10-13 [cm3/molecule s] (T/298 K)3.55 e-20999 [J/mole]/RT
Category:  Theory
Data type:   Transition state theory
Comments:   Energies of the transition state are reported from ab initio UQCISD(T)//MP2/6-311G(2d,p) level calculations. chosen. The rotational partition functions were calculated classically,and thevibrational modes were treated as quantum-mechanical separable harmonic oscillators. Only thecentrifugal-dominant small-curvature tunneling effect correction method was used in our calculation of the rate constant.
