Correlation of Molecular Constants. II. Relation between Force Constant and Equilibrium Internuclear Distance

Abstract

A new relation between force constant and equilibrium internuclear distance has been suggested: $$k_e{\mathrm{(r}}_e{\mathrm{-d)}}^2\mathrm{=A,}$$ where d and A are constants for each molecular group. The relation has been examined for a number of molecular groups and found to be satisfactory.
