Developement of semiclassical methods of calculating vibration-rotation molecular spectra popup.stage_title Head Nesterenko Oleksandr I., Доктор фізико-математичних наук Registration Date 22-11-2021 Organization Ukrainian State University of Chemical Technology popup.description2  The object of study - the rotational spectra of molecules with symmetry; cracking of oil products in cavitation conditions; charged black holes; hydraulic transport systems; wastewater treatment in bioreactors. The purpose of the work is to build a mechanism for changing the structure and composition of phases in multiphase systems under non-stationary conditions. Development of quasiclassical theory of oscillatory-rotational spectra of molecules. Research methods - mathematical methods of theoretical physics; Numerical Methods; mathematical modeling. An effective model of the evolution of a multiphase system in nonstationary conditions is obtained. A method for improving the accuracy of calculating the rotational energies of molecules to identify high-resolution spectra has been developed. A mathematical model of migration processes of groundwater and atmosphere pollution has been created. A method for calculating the parameters of hydraulic transport in polyethylene pipes is proposed. The influence of how the cosmological constant affects the horizons and structure of R - and T - regions in spherically symmetric solutions for charged black holes has been studied.
