For the vibration-rotational motion of a diatomic molecule, various forms of an effective Hamiltonian which includes the corrections of the Born-Oppenheimer approximation in the form of radial functions are reviewed. A procedure to fit vibration-rotational and pure rotational transitions is proposed

The potential model of G. Thompson et al. [J. Mol. Spectrosc. 124, 130-138 (1987)] for an analysis of the vibrational-rotational and the rotational spectra of diatomic molecules is modified by an algebraic WKB treatment of the Schro ¨dinger equation given by Watson's effective Hamiltonian. A compact
We combined radial functions for the rotational g-factor and electric dipole moment, from molecular electronic computations but tested with experimental data, with spectral data of 557 pure rotational and vibration-rotational transitions of LiH in four isotopic variants; on this basis we evaluated s
