Scattering of low-energy electrons by polar molecules: An analytic approach
(American Physical Society, 1998)
The scattering of low-energy electrons by polar molecules is considered. The excitation to the rotational states in the sudden approximation and the effect of the Coulomb dipole force to all orders are taken into account. ...

On the relation between algebraic and configuration space calculations of molecular vibrations
(Elsevier, 1996-03)
The relation between algebraic and traditional calculations of molecular vibrations is investigated. An explicit connection between interactions in configuration space and the corresponding algebraic interactions is established.

Comment on “Boson-realization model for the vibrational spectra of tetrahedral molecules”
(American Physical Society, 1997)
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)]. Because of the local nature of the bosons ...

A general algebraic model for molecular vibrational spectroscopy
(Elsevier, 1996)
We introduce the anharmonic oscillator symmetry model to describe vibrational excitations in molecular systems exhibiting a high degree of symmetry. A systematic procedure is proposed to establish the relation between the ...

A symmetry adapted approach to vibrational excitations in atomic clusters
(Springer Nature, 1998)
An algebraic method especially suited to describe the strongly anharmonic vibrational spectra in molecules may be an appropriate framework to study the vibrational spectra of Na+n clusters, where nearly flat potential ...

A Symmetry-Adapted Algebraic Approach to Molecular Spectroscopy
(Scielo, 1996)
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 and configuration space formulations. In ...

Métodos algebraicos en física molecular: el modelo de osciladores anarmónicos simetrizados (AOSM) para el estudio de la estructura vibracional y una aproximación analítica a la dispersión de electrones por moléculas polares.
(1998)
En esta Tesis se presentan los resultados del trabajo realizado durante cuatro años en el Instituto de Ciencias Nucleares de la Universidad Nacional Autónoma de México y el Departamento de Física Atómica, Molecular y Nuclear ...
