Nowadays, one of the most important research fields in chemistry is the study of large systems. In this sense, one of the most active research areas is the field of supramolecular chemistry, chemistry of big molecules (Atwood and Lehn 1996), which involves the use of noncovalent interactions to assemble molecules into stable, well-defined structures and which plays an important role in biological processes. Thus, it is crucial to examine the interactions between molecules and their environment. Well-known systems include host-guest and protein-substrate complexes, molecular clusters, or simply molecules within their medium.

Currently, there is great interest in the theoretical study of supramolecular systems. Molecular modeling includes all theoretical methods and computational techniques used to model or mimic the nature. The techniques are used in the fields of computational chemistry...
