a ∆E (AB), ∆E (BC), and
∆E (ABC) are the interaction energies of A…B, B…C,
A…B…C complexes, respectively.
∆E (A-C)far is the interaction energy between two
unbonded molecules in the A…B…C ternary system. ∆∆Eis the difference of ∆E in the ternary complex relative to the
corresponding binary complex.
