heterolytic bond-dissociation energy

The energy required to break a given bond of some specific compound by heterolysis. For the dissociation of a neutral molecule AB in the gas phase into A+ and B the heterolytic bond-dissociation energy D(A+B) is the sum of the bond dissociation energy, D(A–B), and the adiabaticionization energy of the radical A. minus the electron affinity of the radical B..
