dc.description.abstractLa predicción de los modos de vibración de las moléculas o estructuras cristalinas basados en sus propiedades de simetría, nos permiten utilizar un poderoso método para caracterizar nuevos materiales. En el siguiente trabajo, se realizó el análisis modal teórico por medio del método de correlación, y se obtuvo los modos de vibración Raman opticamente activos para un sistema cristalino con estructura de tipo Hexagonal Wurzita. Utilizando la técnica de espectroscopia Raman, se registró el espectro de vibración Raman Stokes para un cristal de ZnO. A partir del análisis teórico y del espectro Raman registrado experimentalmente para el ZnO, se pudo observar y comparar el método teórico (método de correlación) con el experimental (técnica de espectroscopia Raman). Este análisis, sugiere que el método de correlación es preciso en la predicción de los modos de vibración de cualquier red cristalina, sin embargo, su poder se puede extender al usarse conjuntamente con los datos experimentales Raman en la caracterización de la calidad cristalina y estructural de nuevos materiales de interés tecnoló

dc.description.abstractenglishThe prediction of vibrational modes of the crystalline molecules or structures based on their properties of symmetry, allow us to use a powerful method to characterize new materials. In this work, the theoretical modal analysis was performed by the correlation method, and the optically active Raman vibration modes were obtained for a crystalline system with hexagonal Wurzite type structure. Using the Raman spectroscopy technique, the Raman Stokes vibration spectrum was obtained for a ZnO crystal. From the theoretical analysis and the experimentally recorded Raman spectrum for ZnO, it was possible to observe and compare the theoretical method (correlation method) with the experimental method (Raman spectroscopy technique). This analysis suggests that the correlation method is accurate in predicting the modes of vibration of any crystal lattice, which can be used in conjunction with the Raman experimental data in characterizing the crystalline and structural quality of new materials of technological
