Abstract

In the series of articles we have developed a semiclassical self-consistent approach to calculation of the highly excited rotational states in vibration-rotation (VR) spectra of polyatomic molecules. The central idea of the semiclassical approach is based on the introduction of the auxiliary time-periodical fields which transfer interactions between rotational and vibrational molecular degrees of freedom. This procedure leads to separation of variables in the VR Hamiltonian and, as a result, to simplification of the initial problem interpretation, which is reduced now to an independent solution of two nonsteady Schrodinger equations. In the first of them the Hamiltonian describes a motion of the molecular angular momentum J in some time-periodical field and does not depend on the vibrational coordinates explicitly, in the second - the Hamiltonian is a sum of usual vibrational energy and some additives, which describe a motion of the vibrational collective variables in auxiliary fields and do not depend on the angular coordinate explicitly.
