What is the BDE

The homolytic BDE is defined as the enthalpy change in the following fission  

The BDE, Dff°(R —X), of a R—X bond is derived in the usual way from the heats of formation of the species involved in the above reaction  

In this case, AfH° represents the heats of formation of the respective species in the ideal gas state at standard pressure and at a reference temperature of 298.15 K. 

Therefore, the BDE is also called the bond dissociation enthalpy. Here, species RX represent molecules, radicals, ions, and complexes, as well as clusters. The BDEs are commonly referred to as bond energies, bond strengths, binding energies, or bond disruption energies (enthalpies). The BE or D are other simplified abbreviation of the BDE in the literature. 

In this volume, varied processes of the bond dissociation are included, such as
