    "abstract": "We discuss a symmetry-adapted algebraic (or vibron) model for molecular\nspectroscopy. The model is formulated in terms of tensor operators under the\nmolecular point group. In this way, we have identified interactions that are\nabsent in previous versions of the vibron model, in which the Hamiltonian is\nexpressed in terms of Casimir operators and their products. The inclusion of\nthese new interactions leads to reliable spectroscopic predictions. As an\nexample we study the vibrational excitations of the methane molecule, and\ncompare our results with those obtained in other algebraic models.",
