Single crystals of Sr5(PO4)3Cl doped with Mn(V) ion were prepd. by the std. flux-growth technique. The polarized electronic spectrum (8000-44,000 cm-1) of MnO43- in Sr5(PO4)3Cl was measured at 4.2 K. By means of a careful examn. of the possible excited states and of the site-symmetry of the Mn(V) ion, the bands in the region 8000-23,000 cm-1 are assigned as ligand-field transitions and the others at higher energy, which are more intense, as charge-transfer transitions. These assignments are based on the obsd. polarizations of the bands and on their oscillator strengths.
