The Logical Position of the ``Average Bond Energy,'' the ``Dissociation Energy of a Bond,'' and the ``Force Constant''

The concepts of ``bond dissociation energy'' and ``average bond energy'' are analyzed. A mathematical treatment is suggested which makes it possible in principle to distribute the energy of atomization among the various bonds of the molecule. The relationship between the ``bond dissociation energy,'' ``average bond energy,'' and ``reorganization energy'' is examined in the light of various molecular force fields.
