The energetic corrections included in the focal point analysis (Tables ) behave uniformly across all stationary points and indicate no anomalous features of this system. The ZPVE corrections are the largest and are no greater than 5.5 kcal mol -1 with transition state ZPVE corrections generally closer to 1.5 kcal mol -1 . The frozen core and scalar relativistic corrections are both small and never larger than 0.24 kcal mol -1 . The DBOC corrections are negligible and indicate that none of the stationary points is in the vicinity of a conical intersection or surface crossing. In all cases, excellent convergence is exhibited with respect to basis set and higher order coupled cluster terms. These results affirm that our predictions are well within the bounds of chemical accuracy (i.e. one kcal mol -1 ) with respect to our electronic energies.
