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..
