    • For this subset of bonds the empirical correction, prescribed in ref 36a, to the BDEs amounts to +0.1 kcal/mol for X-halogen bonds and -3.2 kcal/mol for all of the other bonds.

    • note
    • Incidentally, because the mB3LYP approach (as described in ref 37a) includes empirical corrections for the difference in the number of α- and β-electrons and the number of lone-pairs and π-bonds, it is impossible to use the method consistently over a reaction coordinate where the number of these types of electrons is changing. For example, mB3LYP cannot be used to describe the reaction coordinate associated with the addition of the methyl radical to ethylene because the π-bond is lost at an underfined point along the reaction coordinate.
