Abstract

We extend our recently developed inversion method to extract excited state potentials from fluorescence line positions and line strengths. We consider a previous limitation of the method arising due to insufficient input data in cases where the relatively weaker emission data are not experimentally available. We develop a solution to this problem by "regenerating" these weak transition lines via applying a model potential, e.g. a Morse potential. The result of this procedure, illustrated for the Q-branch emission from the lowest three vibrational levels of the B$1 Πstate of LiRb, is shown to have an error of0.29cm^{-1}in the classically allowed region and a global error of5.67cm^{-1}forV\le Eν'=10$. The robustness of this procedure is also demonstrated by considering the statistical error in the measured line intensities.
