✦ Synopsis

Degeneracies resultmg from dynamical symmetrres rn the coupling of anharmonic oscillators are mvestrgated rn terms of an SLJ(6) algebraic model for benzene local modes. Predicted combination and overtone spectra are discussed for u = 2 levels of Cds and C&. The latter has an approximate W(3) X W(2) X U(1) dynamical symmetry for the mode couphng, resulting in appro.ximate degeneracies beyond those required by Deb symmetry. It is conJectured that dynamical symmetries for the coupled, anharmonic hamiltonian account for these degeneracies of coupled, anharmonic systems

The stretching and bending vibrations of methane are described in a local-mode anharmonic symmetry adapted model. Both Hecht-and Fermi-like interactions are considered. We start by establishing the Hamiltonian of the system in terms of internal coordinates and momenta. The Hamiltonian is then rewrit
