Query: A symmetry-adapted algebraic approach to molecular spectroscopy   We apply a symmetry-adapted algebraic model to the vibrational excitations in
D_3h and T_d molecules. A systematic procedure is used to establish the
relation between the algebraic and configuration space formulations. In this
way we have identified interaction terms that were absent in previous
formulations of the vibron model. The inclusion of these new interactions leads
to reliable spectroscopic predictions. We illustrate the method for the D_3h
triatomic molecules, H_3^+, Be_3 and Na_3, and the T_d molecules, Be_4 and
CH_4.
