Abstract
Analytical expressions for the rotational-vibrational energy levels of diatomic molecules represented by the Tietz-Hua rotating oscillator a re derived using the Hamilton-Jacoby theory and the Bohr-Sommerfeld qu antization rule. In molecules with moderate and large values of rotati onal and vibrational quantum numbers, the levels are in much better ag reement with the results of numerical calculations than the energies o btained from the common model of the rotating Morse oscillator.
