The purpose of the work is an experimental and theoretical study of electron-oscillation processes in 1D and 2D-dimensional nanosystems (carbon nanomaterials, dichalcogenides of transition metals, hybrid nanocomposites based on them) to establish the influence of the type of symmetry, dimensionality, and structural changes on the regularity of the course of nonlinear resonant wave interactions in these systems, which are the basis for the development of fundamental principles for the creation of polymer multicomponent nanocomposites with controlled and improved optical, electrical, magnetic, etc. properties depending on the field of application, as fillers in which it is planned to use 1D and 2D-dimensional carbon graphite materials and DHPM, semiconductor and metal (plasmonic) nanoparticles, small molecules, linear π-electron conjugated systems. Research methods – methods of the theory of symmetry groups, Raman spectroscopy, spectrophotometry, photoluminescence, methods of quantum chemistry. Liquid systems of C60 and C70 fullerenes, 1D and 2D carbon graphite materials and graphene-like nanoparticles of dichalcogenides of transition metals MX2 (M=Mo, W; X=S, Se) were studied; studied the energy spectra of oscillatory excitations in these structures and their dispersion.
