Comments:
1) The rate coefficent is the result of BHandHLYP/6-311G(d,p) calculations. The paper also lists rate coeffients computed at the MP2/6-311G(d,p) level.
The title reactions was modeled using ab initio MP2 and a hybrid density functional method (BHandHLYP) methods, and the 6-311G(d,p) basis set. Single-point calculations at the CCSD(T) level were carried out at the optimized geometries. Hindered Internal Rotation partition functions calculations were explicitly carried out and included in the total partition functions. The explicit participation of the tunnel effect was taken into account.
