This is the case even in the simplified method (Ref. 6) in which the CP correction is determined by computing the energy of every fragment in the overall basis of the cluster. If one uses the more correct "hierarchical" scheme of CP corrections (Refs. 7 and 8) then the number of calculations required for the CP treatment increases astronomically. (For a recent discussion of different CP schemes see Ref. 9).

Integrals of intermonomer type are those for which the two Orbitals in the "ket" belong to different subunits. For a general two-electron integral with four different indices one integral value actually computed represents eight different integrals. It may well happen that some of them are of intramonomer and other of intermonomer type.

In Fig. 3 the uncorrected A" curve is very close with the corrected A' ones. This is merely a coincidence, as it is indicated by the results of the calculations with the larger basis set, shown in Fig. 5.

We are grateful to the Referee who called our attention to the fact that Eq. (15) can be obtained by referring to the stationary properties of the Hylleraas functional, instead of the somewhat involved original derivation given in Ref. 24.

Real systems differ from our simplified model, leading to some differences between the CHA/CE and CP results, especially if small basis sets are used. This problem is, however, out of our present scope.

It is only the case of binary complexes with no avoided crossings for which it is immaterial whether one uses Eq. (10) or Eq. (11). Some more complex cases in which Eq. (11) is clearly preferable have been mentioned in Ref. 3. A further advantage of the interpretation based on Eq. (11) is that it allows for a straightforward analytical definition of any CP-corrected quantity that depends on the total energy or its derivatives - Refs. 32, 33 (gradients, dipole moments, vibrational frequencies, polarizabilities, etc.) as it is realized by one of us in the recent version of the GAUSSIAN program system (Ref. 34).
