The scientific significance of the research results lies in the fact that the results analyzed in this work on modern theories of spectroscopy and quantum chemical calculations make it possible to further intensify the physical understanding of the spectroscopic nature of weak intermolecular interactions, as well as to interpret the specific aspects of weak hydrogen bonds involved in formation of complexes in molecules with amino groups, based on a single approximation.
The practical significance of the research results is that the results obtained are important for explaining the physical properties of complex biological systems, solving the problem of creating new materials, determining the electro-optical parameters of molecules, and monitoring changes in the thermodynamic parameters of condensed matter.
