A periodic table of free diatomic molecules—II predicted internuclear separations from curve-fitted data

Recent theory substantiates the stacking order of the areas in the recently proposed periodic table of the free diatomic molecules. The periodic table suggests curve-fitting algorithms for r_e which, after semi-empirical perturbations yield ground-state values for r_e which agree with literature values and with those from an alternate algorithm to from 5 to 8%. 800 predicted r_e extend to superheavy quasimolecules and to molecules with superheavy atoms, and many pertain to molecules of laser interest.
