Determination of Bond-energy Terms in Phosphorus-containing Compounds

The enthalpies of formation of a series of phosphorus containing compounds were calculated using various ab initio quantum chemical methods adapted to the size of the species under consideration. A large variety of bond energy terms involving the phosphorus atom were derived from the corresponding enthalpies of atomization. Some interesting applications of these bond energy terms, namely the determination of stabilization energies, pi-bond energies and Pauling's electronegativities, are also described.
