A diagram which shows the relative energies of orbitals, configurations,
valence bond structures, or states of reactants and products of a reaction, as a function
of the molecular geometry, or another suitable parameter. An example involves the
interpolation between the energies obtained for the united atoms and the values for
the separated atoms limits.
