Abstract
The Franck-Condon (FC) factors (transition probabilities) and r-centroids have been evaluated by the more reliable numerical integration procedure for the bands of A3 Πi- X3 Σ- system of molecule PD, using a suitable potential. The dissociation energy for the electronic ground state of PD molecule has been estimated by fitting the empirical potential function to the experimental potential energy curve, using correlation coefficient.
Keywords: Franck-Condon factors and r-centroids; dissociation energy; PD molecule.
Resumen
Los factores de Franck-Condon (probabilidades de transición) y los centroides r han sido evaluados por el método de integración numérica más confiable para las bandas del sistema de molécula PD A3 Πi- X3 Σ- usando un potencial adecuado. La energía de disociación para el estado base de la molécula PD ha sido estimada ajustando la función empírica del potencial a la curva de energía experimental, usando el coeficiente de correlación.
Descriptores: Factores de Franck-Condon y centroides r; energía de disociación; molécula PD.
