The work purpose – working out of methods of calculation of vibration-rotation states of nonrigid molecules with inversion and torsion motion, development semiclassical methods of calculating high-excited states of molecules; the proof of possibility of use cavitation for cracking oil hydrocarbons; to establish dependence of solubility oxides of metals from their characteristics; working out of the approximate analytical solutions of problems of non-stationary heat conductivity for multilayered bodies at extreme thermal influences; working out of methods of neutralization of pollution of underground waters. A research method – mathematical methods of theoretical physics; the approximate analytical methods of operation calculation, method of power series, and also numerical methods; mathematical modeling. The new exact quantum-mechanical Hamiltonian has been derived for the nonrigid molecules making inversion and torsion motion. The semiclassical method of calculating high-excited vibration-rotation energy levels of molecules was developed. These results can be used for practically important problem of decoding molecular spectra. Possibility of cracking hydrocarbons of oil by hydrodynamic cavitation was shown. The detailed analysis of this possibility has allowed to make the optimistic forecast about possibility to increase depth of processing hydrocarbons of oil on 20–30%. Semiempirical expression for hierarchy of solubilities of oxides of metals in zirconium dioxide is received, that is important for reception of solid high-temperature electrolyte. The mathematical model of calculating temperature fields of a multilayered construction was developed at extreme thermal influences. The problem of non-stationary heat conductivity was solved at extreme exposures. With reference to local conditions schemes of active influence are developed – physical and chemical neutralisation of areas with the raised maintenance of sulphates, and also constant monitoring of underground waters for the control over distribution radionuclides from radioactive waste storage of products of processing uranium ores, that is important for ecological safety of region.
