Abstract
The relations between spectroscopic constants of the series for the energies of vibration-rotational states of a diatomic molecule constructed in references 1 and 2 and the constants Yij of the Dunham series are reported. The precise experimental data on the energy levels of the molecular HCl comprising practically all the discrete vibration-rotational spectrum in the ground electronic state were treated. It has been proved that the series constructed in references 1 and 2 possesses much better convergence and predicting ability than the Dunham series and enables one to derive the Yij constants from the adequate treatment of the whole set of experimental data concerning to the discrete spectrum of a molecule.
