For a diatomic molecule, the maximum vibrational energy that a molecule can have prior to its decomposition
into the ground electronic states of the constituent
atoms (spectroscopic bond-dissociation energy
value is related to the chemical dissociation
is zero-point vibrational energy. This definition is usually extended to the dissociation
of polyatomic molecules into certain molecular fragments through homolytic or heterolytic bond cleavages.
