摘要：

Using angular-momentum-projected mean-field theory, we develop 1/N expansion solutions for the vibron model of diatomic molecules. Analytic expressions of spectroscopic accuracy are derived for rotational vibrational energy levels and for the intensities of transitions among them. The results are used in a systematic study of diatomic molecules in the vibron model with a view to finding appropriate Hamiltonians for a realistic description of rotation-vibration spectra.
