@article{Wertheim1984FluidsWH, title={Fluids with highly directional attractive forces. I. Statistical thermodynamics}, author={M. S. Wertheim}, journal={Journal of Statistical Physics}, year={1984}, volume={35}, pages={19-34} }

A new formulation of statistical thermodynamics is derived for classical fluids of molecules that tend to associate into dimers and possibly highers-mers due to highly directional attraction. A breakup of the pair potential into repulsive and highly directionally attractive parts is introduced into the expansion of the logarithm of the grand partition function in fugacity graphs. The bonding by the directional attraction is used to classify the graphs and to introduce a topological reduction…
