… will oscillate about an average internuclear separation. If the oscillation is harmonic, this average value will not change as the vibrational state of the molecule changes; however, for real molecules the oscillations are anharmonic. The potential for the oscillation of a molecule is the electronic energy plotted as a function…

…molecule, in which only the internuclear distance is variable, is shown in Figure 10. The energy minimum of this curve corresponds to the observed bond length of the molecule. The depth of the minimum is (apart from a small correction for the vibrational properties of the bond) equal to the…
