The Franck-Condon factors (vibrational transition probabilities) and r-centroids have been evaluated by a more reliable numerical interogation procedure for the bands of b1Σ+ - X3Σ- system of the PF molecule, using a suitable potential. The dissociation energy, De = 318 kJ mol-1 for the electronic ground state of this molecule has been estimated by fitting the electronegativity function to the experimental potential energy curve.
