DIPOLE POLARIZABILITY AND BOND-DISSOCIATION ENERGY

The change of thermodynamic equilibrium-state functions, such as the c hange in enthalpy Delta H or free enthalpy Delta G, in bond dissociati on processes is well known in general. On the other hand, the systemat ic investigation of the change in electrical and electro-optical prope rties, such as the dipole polarizability alpha, seems to be a rather u nexplored field in physical chemistry. In this Communication we report on a remarkable correlation between the change in dipole polarizabili ty Delta alpha and the bond dissociation energy D-298(0) for various d issociation processes.
