    • 2v were both found to be transition states. With inclusion of electron correlation [MP3/MP2/6-31+G(d)], the tetrahedral TS was energetically favored. However, the planar σ TS is also a second-order saddle point at the MP2 as well as the B3LYP level. Analytical second derivatives were not available to confirm the earlier saddle points.

    • The proton affinity of methanol at the B3LYP/6-311+G-(d,p)+ZPVE level is 178.8 kcal/mol and that of acetyl chloride is 174.0 kcal/mol. The PA of water is lower at 168.9 kcal/mol. The PA of the carbonyl oxygen of methyl acetate is calculated to be 190.9 kcal/mol at this level.
