Phenomenological characterization of the isomerization transition state of carbonyl sulfide
Amine Rafik, Jamil Khalouf-Rivera, F. Pérez-Bernal +2
Signatures of excited-state quantum phase transitions in the bending degree of freedom of triatomic systems that undergo an isomerization reaction have been recently evinced. In th…
Calculation of Transition State Energies in the HCN-HNC Isomerization with an Algebraic Model
Jamil Khalouf-Rivera, Miguel Carvajal, Lea F. Santos +1
Recent works have shown that the spectroscopic access to highly-excited states provides enough information to characterize transition states in isomerization reactions. Here, we sh…
Algebraic theory of endohedrally confined diatomic molecules: application to H@C
Lorenzo Fortunato, Francisco Perez-Bernal
A simple and yet powerful approach for modeling the structure of endohedrally confined diatomic molecules is introduced. The theory, based on a u(4)+u(3) dynamical algebra, combine…
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 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…
Comment on ``Boson-realization model for the vibrational spectra of tetrahedral molecules''
R. Lemus, F. Perez-Bernal, A. Frank +2
An algebraic model in terms of a local harmonic boson realization was recently proposed to study molecular vibrational spectra [Zhong-Qi Ma et al., Phys. Rev. A 53, 2173 (1996)]. B…
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^+.
A symmetry-adapted algebraic approach to molecular spectroscopy
A. Frank, R. Lemus, R. Bijker +2
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…
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…
