    • (a) Unless otherwise noted, the basis sets that were used were internal to MOLPRO. Because of an error within MOLPRO, the aug-ccp-CVQZ basis set for oxygen was obtained from the Extensible Computational Chemistry Environment Basis Set Database, version 10/11/01, as developed and distributed by the Molecular Science Computing Facility, Environmental and Molecular Sciences Laboratory, which is part of the Pacific Northwest Laboratory, P.O.

    • 2 we used the 6-31G(d) basis sets for K and Ca from ref 5 while in the present work we use the subsequently developed 6-31G(d) basis sets for K and Ca of Rassalov et al. from ref 44b. The latter are the basis sets used in the formulation of G3 for third-row elements.

    • Roos, B. O., Ed.; Springer-Verlag: Berlin. These comments appear to apply more to the correlation-consistent basis sets (see, however, ref 47) than to those based on 6-3IG, for which MP2(full) has been widely used without (as far as we are aware) significant documentation of misbehavior
    • Taylor has previously commented, "Using valence-optimized basis sets and including core-correlation is not only a waste of computer time, but a potential source of problems, as it can substantially increase BSSE. This point is not well appreciated: the prevailing view appears to be that no harm can come of correlating the core when the basis set is inadequate. This is not so." See Taylor, P. R. In Lecture Notes in Quantum Chemistry; Roos, B. O., Ed.; Springer-Verlag: Berlin, 1992; p 406. These comments appear to apply more to the correlation-consistent basis sets (see, however, ref 47) than to those based on 6-3IG, for which MP2(full) has been widely used without (as far as we are aware) significant documentation of misbehavior.

    • f 298 from the value in Table 13 arises because of the Q5 extrapolation for the (T) component as opposed to the standard TQ extrapolation for this component.
