ABSTRACT
Neither qualitative nor quantitative description of the processes proceeding in the liquid phase can be given without detailed determination of intermolecular interactions. "Intermolecular forces are responsible for the liquid phase existence and occurrence of the overwhelming majority of chemical structures such as ions, ion pairs, complexes, micelles, etc. On the other hand, they exert a substantial effect on the physicochemical properties of molecules: from relatively simple variation of activity to conservation and transmission of genetic codes. Therefore, virtually no experimental data can be interpreted without understanding of the importance of the intermolecular forces involved in this event. In spite of the extreme complexity of the problem, this importance must be determined. However, in spite of significant theoretical progress in this area and application of sophisticated experimental techniques based on highefficiency computers, these problems remain obscure and investigators should use model systems" [1].
