| An attempt at including the centrifugal distortion effect in description of the rovibrational states of diatomic systems with a molecular potential approximated by the Morse function is presented. The derived Schrödinger equation can be rigorously solved leading to the eigenvalues in the form of a continued fraction, which are applied for evaluation of the molecular constants and for prediction of the rovibrational spectra of the selected diatomic molecules giving quite satisfactory reproduction of the experimental data. A simple extension of the method developed, by assuming the rotational dependence of the dissociation constant, is also proposed. |
