DETERMINATION OF BOND-ENERGY TERMS IN PHOSPHORUS-CONTAINING COMPOUNDS

The enthalpies of formation of a series of phosphorus containing compo unds were calculated using various ab initio quantum chemical methods adapted to the size of the species under consideration. A large variet y of bond energy terms involving the phosphorus atom were derived from the corresponding enthalpies of atomization. Some interesting applica tions of these bond energy terms, namely the determination of stabiliz ation energies, pi-bond energies and Pauling's electronegativities, ar e also described.
