Estudio teórico del espectro rovibracional del trímero de Argón.
The Ar system has been studied by means of an exact quantum mechanical variational method based in the use of distributed Gaussian functions to describe the interparticle Ar-Ar distances. This work includes the rovibrational levels spectra for the zero total angular momentum, J=0, case and for J=1....

This work includes the rovibrational levels spectra for the zero total angular momentum, J=0, case and for J=1. In order to describe the rotational part, we have used an approximate method in which the eigenfunctions obtained in the purely vibrational problem are employed in the solution of the J > 0 case. Besides the energy levels, rotational constants have been calculated. Different approaches for the calculation of such constants are comparatively analysed. El sistema Ar se ha estudiado mediante un método variacional cuántico exacto basado en la utilización de funciones Gaussianas distribuídas para describir las distancias interatómicas Ar-Ar. Este trabajo contiene el espectro de niveles rovibracionales del trímero para el caso en el que el momento angular total J sea o 0 ó 1. Para describir la rotación, se ha empleado un método aproximado,donde las autofunciones radiales del caso estrictamente vibracional, se utilizan en la resolución aproximada del problema en el que J > 0. Además de los niveles energéticos, se han calculado las correspondientes constantes rotacionales asociadas a los mismos. Dos posibles métodos para obtener dichas constantes son analizados en detalle. pubtype: Academic Journal doctype: Article src: R language: Spanish refInfo: copyright: @attributes: flag: Y custom: Copyright of Revista Cubana de Física is the property of Universidad de La Habana and its content may not be copied or emailed to multiple sites without the copyright holder's express written permission.
