Bond dissociation energy phosphorous

The bond dissociation energy (BDE) for breaking the carbon-phosphorous bonds is much smaller (D = 128.6kcalmol" ) than the interaction energy AEj ,. 

Morton and Beckett, in an appendix to their book, present bond dissociation energies and standard electrode potentials. Brown, in his book, which is mainly concerned with the techniques of microcalorimetry, gives values of A/ff, AGf, S°, and C° (for 25 °C) for many biological substances, and partial molar properties for aqueous solutions. He also presents enthalpies and Gibbs energies of formation of adenosine phosphoric acid specimens and thermodynamic quantities for some reactions in solution.
