Previously reported spectra of the pentaphosphates of Nd3 and Eu3 are analyzed by diagonalizing a parametrized C sub S C sub 1h Hamiltonian in free-ion bases involving the five and seven lowest J-multiplets, respectively, of each ion. By reassigning symmetries to the reported Eu levels according to predictions from scaled crystal field parameters, B sub km, that fit 28 Nd3 levels to 7.61 cm, a fit of 10.43 cm to 46 Eu3 levels is obtained. Predicted B sub km and energy levels for all the lanthanide pentaphosphates are then obtained.
