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
adiabatic
ionization energy
of the radical
A
.
minus the
electron affinity
of the radical
B
.
