The stretching and bending vibrational spectrum and the intensities of infrared transitions in a tetrahedral molecule are studied in two boson-realization models, where the interactions between stretching and bending vibrations are described by a quadratic cross term and by Fermi resonance terms, ca

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 effects of head-tail coupling in the mechanism of formation of combinations and overtones of perpendicular vibrational modes, in molecules like ethane and methanol, is investigated. For uncoupled head and tail the perpendicular modes have higher degeneracies, and the species of the components of
