It is shown that the decrease of the Lif affiitien upon proBessive meehylation of ammonia is accounted for by ab initio computations and art explanation is given for the reversal of this order with respect to that of the proton affinities, in term of the different evolution of the components of the
## Abstract Correlated ab initio calculations on large systems, such as the popular MP2 (or RI‐MP2) method, suffer from the intramolecular basis set superposition error (BSSE). This error is typically manifested in molecules with folded structures, characterized by intramolecular dispersion interac
