P 2p3/2 - P 2p1/2 splitting value is 0.86 +/- 0.05 eV. [2] has it at 0.84 eV.
Note:
(PO4)3- = phosphate
(P2O7)4- = pyrophosphate
(PO3)- = metaphosphate

Update: Recent work on stoichiometric Li3PO4 films gave P 2p3/2 binding energies of between 133.20 to 133.35 eV with FWHM of ~1.2 eV. Li 1s was at 55.26 to 55.52 eV with FWHM of 1.4 eV.
