Chemical Shifts of Auger Electron and Photoelectron Binding Energies of Phosphorus in Solid Compounds

A set of experimental 1s, 2s, and 2p photoelectron binding energy and KL2,3L2,3; 1D2 Auger energy shifts of phosphorus in 11 solid compounds referenced to elemental red phosphorus is presented. Correlations between the shifts are discussed. The Auger parameters, ξ, are used to estimate the changes in the extraatomic static relaxation energy ΔR . Line shifts and ΔR values are compared with differences in Pauling's electronegativity between phosphorus and the neighbouring atoms and averaged atomic electronic polarizabilities of the neighbours. Absolute R values are calculated and compared with data of gaseous P compounds which provides a systematic difference.
