In recent years, hydrogen bonding has attracted great interest in the world as a special type of interaction that plays an important role in the existence of biomolecules. After all, its manifestation in vibrational spectra has not yet been fully explained. Consequently, the interaction of molecules in condensed states of matter and the mechanisms of formation of molecular clusters are becoming increasingly important in the world. From this point of view, the mechanisms of formation of molecular clusters with hydrogen bonds in biological objects in a condensed state, important for life, and the general laws of intermolecular interactions, as well as the vibrational spectrum of these molecular clusters under the influence of the definition of the light field remain one of the important factors determining the development of the field .
The results obtained from vibrational spectra expand the understanding of intermolecular interactions and are used to solve problems of the formation of molecular clusters in the liquid state of matter. It is important to develop methods of molecular spectroscopy when studying the macroscopic properties of substances, the role of molecular clusters, and the problems of intermolecular hydrogen bonds. These studies contribute to the development of the molecular theory of the liquid state of matter, which, in turn, expands the possibilities for the targeted use of liquid media for industrial needs.
The practical significance of the research results lies in the fact that the formation of molecular clusters using hydrogen bonds is important in the life of living organisms. Hydrogen bonding is widespread in biopolymers. Therefore, this type of research helps to better understand the role of hydrogen bonds in these processes. The established laws make it possible to describe the property of a spectroscopically active molecule based on a change in the contour of its vibrational band when the environment changes. A connection has been established between the parameters of the strip contour and the parameters characterizing the properties of the medium, which is important for complex systems.
