    • v symmetry with the TZ2P basis set on an eight-processor 2.8 GHz machine required 38 s with the PBE functional. Starting from the same geometry, we found optimization with the B3LYP functional required 56 min 32 s.

    • It should be noted that in the energy decomposition sheme used here, interactions are categorized with respect to being within or between fragments. In particular, "polarization" is a phenomenon that refers to the mixing of occupied and virtual orbitals within the same fragment. "Charge transfer" represents the interactions between the occupied molecular orbitals of one fragment and the unoccupied molecular orbitals of the other fragment.

    • A somewhat more sophisticated model involving the cosine of the θ angle was also explored, but it did not provide appreciably better correlation with the binding energy.
