heterolytic bond-dissociation energy

https://doi.org/10.1351/goldbook.H02810
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 adiabatic ionization energy of the radical A· minus the electron affinity of the radical B·.
