| On the basis of the deformable body model and harmonic potential approximation, a nonlinear Hamiltonian describing rovibrational states of diatomic molecules has been derived. The proposed approach is extended to include the Simons-Parr-Finlan potential, and the obtained equations are applied in evaluation of molecular constants and in reproduction of rovibrational spectra of the 1Σ state of 12C32S, 13C16O and rotational spectra of 12C16O molecules. A comparison with the standard Dunham results is also made. |
