Influence of interactions of excited vibrations on the molecular parameters

The interaction of vibrations is studied by the algebraic method of perturbation theory. Formulas are derived that take into account the influence of interactions on the anharmonic spectroscopic parameters of excited vibrations with compound frequencies. __________ Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 3, pp. 27–32, March, 2008.
