Universal nature of self-bound potential systems: Diatomic molecules, surface adsorptions, and bulk cohesions

We have determined ${\mathit{a}}_1$/ √Δ and ${\mathit{a}}_2$/Δ for 150 diatomic molecules, 7 physisorptions, and 28 bulk cohesions based on experimental data. It has been shown that those are strongly correlated, and it is impossible to distinguish between the sample distribution patterns from one interaction system to another in the scatter diagram. Here, ${\mathit{a}}_{\mathit{l}}$ (l=1,2,. . .) and Δ are the Dunham coefficients and Sutherland parameter, respectively.
