The absorption and fluorescence spectra of praseodymium-doped lanthanum trifluoride, lanthanum ethyl sulfate, and yttrium aluminum garnet single crystals are reported. The center of gravity of each J level was shifted to the red when the nearest neighbor's of the praseodymium ion changed in the order of fluorine, water, chlorine, bromine, and oxygen. This corresponded to an increase of covalent character by 0.7,0.9, 1.1, and 2.0% for Pr-H/sub 2/O, Pr-Cl, Pr-- Br, and Pr--O bonds when compared with Pr-- F. (auth)
