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 general algebraic model for molecular vibrational spectroscopy
A. Frank, R. Lemus, R. Bijker +2
We introduce the Anharmonic Oscillator Symmetry Model to describe vibrational excitations in molecular systems exhibiting high degree of symmetry. A systematic procedure is propose…
On the relation between algebraic and configuration space calculations of molecular vibrations
F. Perez-Bernal, R. Bijker, A. Frank +2
The relation between algebraic and traditional calculations of molecular vibrations is investigated. An explicit connection between interactions in configuration space and the corr…
