Apart from the classical association approach, two complementary theoretical approaches for hydrogen bond cooperativity have appeared recently in the literature. - The new approach of Veytsman focuses on the combinatorial problem in the simplest possible case a fluid whose molecules have one donor group and one acceptor group with association constants and for the formation of dimers and higher multimers, respectively. The problems associated with the general case are also discussed in earlier work. ... 

Hydrogen bond cooperativity is treated in the work of Sear and Jackson, by including in the association energy a three-body term which either increases or decreases the strength of the bonds in chains of three or more molecules. Their model (in essence, an association model) is able to account for the effect of density on the degree of association and, thus, it can describe vapor-liquid equilibria. 

Let us apply this procedure to hydrogen bond cooperativity.
