@article{Coxon2010TheGX, title={The ground X 1Sigmag+ electronic state of the cesium dimer: application of a direct potential fitting procedure.}, author={J. A. Coxon and P. Hajigeorgiou}, journal={The Journal of chemical physics}, year={2010}, volume={132 9}, pages={ 094105 } }

A collection of 16,544 fluorescence series spectroscopic line positions involving the A (1)Sigma(u)(+)-->X (1)Sigma(g)(+) transition in Cs(2) has been analyzed by a modern direct potential fitting procedure to generate the first fully analytical potential energy function for the ground electronic state, and precise energy term values for the excited A (1)Sigma(u)(+) state. The potential function yields an accurate representation of spectroscopic data that span 99.24% of the well depth and the… Expand
