A symmetry adapted approach to vibrational excitations in atomic clusters
A. Frank, R. Lemus, R. Bijker +2
An algebraic method especially suited to describe strongly anharmonic vibrational spectra in molecules may be an appropriate framework to study vibrational spectra of Na clus…

A general algebraic model for vibrational molecular spectroscopy
A. Frank, R. Lemus, F. Perez-Bernal +2
We present a symmetry-adapted version of the vibron model and discuss an application to D_{3h} triatomic molecules: H_3^+, Be_3 and Na_3^+.

Application of a symmetry-adapted algebraic model to the vibratioinal spectrum of methane
R. Lemus, F. Perez-Bernal, A. Frank +2
The stretching and bending vibrations of methane are studied in the framework of a symmetry-adapted algebraic model. The model is based on the realization of the one-dimensional Mo…
