Time-dependent local-to-normal mode transition in triatomic molecules
Hans Cruz, Marisol Bermúdez-Montaña, Renato Lemus
Time-evolution of the vibrational states of two interacting harmonic oscillators in the local mode scheme is presented. A local-to-normal mode transition (LNT) is identified and st…
A new dynamical group approach to the modified Poschl-Teller potential
Shi-Hai Dong, R. Lemus
The properties of the modified Pöschl-Teller (MPT) potential are outlined. The ladder operators are constructed directly from the wave functions without introducing any auxiliary v…
A comparison between algebraic models of molecular spectroscopy
R. Bijker, A. Frank, R. Lemus +2
We discuss a symmetry-adapted algebraic (or vibron) model for molecular spectroscopy. The model is formulated in terms of tensor operators under the molecular point group. In this…
A local anharmonic treatment of vibrations of methane
R. Lemus, F. Perez-Bernal, A. Frank +2
The stretching and bending vibrations of methane are studied in a local anharmonic model of molecular vibrations. The use of symmetry-adapted operators reduces the eigenvalue probl…
Symmetry-adapted algebraic description of stretching and bending vibrations of ozone
F. Perez-Bernal, J. M. Arias, A. Frank +2
The vibrational excitations of ozone, including both bending and stretching vibrations, are studied in the framework of a symmetry-adapted algebraic approach. This method is based…
A Symmetry Adapted Approach to Molecular Spectroscopy: The Anharmonic Oscillator Symmetry Model
A. Frank, R. Lemus, R. Bijker +2
We apply the Anharmonic Oscillator Symmetry Model to the description of vibrational excitations in and molecules. A systematic procedure can be used to…
