Many diatomic (two-atom) molecules are bound together by covalentbonds that are much stronger than the van der Waals interaction.Examples include H2,O2 and N2 . Experiment shows that for many suchmolecules, the interaction can be described by a force of theform

F(r)=A[e^-2b(r-R0) - e^-b(r-R0)]

where A and b are positive constants, r is the center-to-centerseparation of the atoms, and R0 is the equilibrium separation. Forthe hydrogen molecule A=2.97*10^-8 N ,b= 1.95*10^10 m^-1 andR0=7.4*10^-11 m .
