Аннотация:A procedure for analyzing experimental data in internal rotation problems for predicting the positions of high-level torsional vibrations and correctly assigning them is suggested. The procedure is based on the determination of the anharmonic characteristics of torsional motions in polyatomic molecules. An analogy between the one-dimensional internal rotation model and the properties of low-frequency diatomic molecule oscillators is considered. Experimental data on several types of organic molecules are used to calculate invariant combinations, including the anharmonic constants of torsional vibrations. The resulting equations completely correspond to similar equations for low-frequency diatomic molecule oscillators. They allow anharmonicity of torsional vibrations of poorly studied organic molecules to be estimated. A similar procedure for the internal rotation problem with symmetrical tops uses new reduced Mathieu tables; preliminary S parameter values in these tables can be calculated from the frequency of the 0-1 torsional transition and the structural parameters of the molecule under study.
