Area of scientific interests: software of problems of molecular spectroscopy.

Main results of researches:

1. Abnormal dependence of spectroscopic constant nonrigid molecules on the oscillatory quantum numbers connected with fluctuation of big amplitude in nonrigid molecules is explained.

2. The method of creation of the making functions for effective rotary Hamiltonians of quasilinear nonrigid molecules allowing to improve significantly quality of restoration of experimental ranges of these molecules in comparison with the existing methods is developed.

3. Bi-resonant functions for the theory of shock broadening of spectral lines of molecules are calculated.

4. Analytical representations for coefficients of broadening of lines of molecules are received by pressure of foreign gases.

5. The theory of effective oscillatory and rotary intermolecular potentials of interaction is developed and calculations of broadening of spectral lines of active molecules are carried out by pressure of atmospheric gases.
