Intermolecular regular

In the first category of solutions ( regular solutions ), it is the enthalpic contribution (the heat of mixing) which dominates the non-ideality, i.e. In such solutions, the characteristic intermolecular potentials between unlike species differ significantly from the average of the interactions between Uke species, i.e. 

Recall that regular solution theory deals with nonpolar solvents, for which the dispersion force is expected to be a major contributor to intermolecular interactions. The dispersion energy, from Eq. (8-15), is for 1-2 interactions... 

In principle, another type of collapse, of intermolecular rather than intramolecular origin, might occur whenever four beads (two from one chain, and two from another chain) describe a regular tetrahedron, with side L, on the...
