Abstract: We Performed ab initio calculations on two typical SN2 reactions (1), Fa- +CH3Fb→FaCH3+Fb-, and (2), Cla-+CH3Clb→ClaCH3 + Clb-, for their Minimum Energy ReactionPathways (MERP).It is found that for predicting the correct MERPs and reliable energetic results of these two reactions, the diffuse functions must be included in the selected basis set, and so corrected the errors in previously calculated activation energies for these reactions, especially for reaction (1).

Key words: SN2 reaction, Ab initio, Diffuse function
