摘要：

The electronic absorption and reflectance spectra of Pr(III) ions in molten alkali metal fluorides have been studied. For electronic transitions in the series LiF -> NaF -> KF -> CsF, a long-wavelength shift is observed (nephelauxetic effect). The intensity of the hypersensitive transition (3) H (4) -> (3) P (2) (Delta J = 2) depends on the covalence of the bonds in PrF3- (6) complex species and on their symmetry. The intensity of non-hypersensitive transitions depends only on the symmetry of complex groups.
