What does this research mean for the field?

The bond force constant and internuclear distance of diatomic molecules are accurately related by a specific mathematical expression (k0(re—dij)3 = 1.86×105) that depends on the elements' positions in the periodic table and holds across normal and excited states.

Abstract

It has been found that for diatomic molecules the relation between the bond force constant, k0, and the internuclear distance, re, is quite accurately given by the expression k0(re—dij)3 = 1.86×105, where dij is a constant depending only on the rows in the periodic table in which the two elements comprising the molecule are located. The expression holds not only for the normal state but for all excited states with a few possible exceptions. Some uses of the relation are discussed and an extension to polyatomic molecules is suggested.
