The energy required to break a given bond of some specific compound by @H02809@. For the @D01801@ of a neutral molecule AB in the gas phase into A+ and B the heterolytic @B00699@ D(A+B) is the sum of the @B00698@ energy, D(A–B), and the @A00141@ @I03199@ of the radical A· minus the @E01977@ of the radical B·.
