Microwave spectroscopy of polar molecules, development of programmed microwave  synthesizers of frequency, development microwave spectrometers of various assignment, development nonstandard at stack flue both clusters of a scientific and applied direction, compilation of programs for calculation of the rotation spectrums of polyatomic molecules.

More than 2000 rotary transitions of trance and gauche-form of a molecule of isoproponal for the first time identified and are retrieved optic centrifugal distortion constants of this molecule. The  rotation spectrum of a molecule  (HD₃)₂CDOH for the first time identified. The hybrid spectrometer is created on the basis of the designed cross-section synthesizer of frequencies.
