✦ Synopsis

The absorption and circular-dichroism (CD) spectra of LaBGeO 5 ÀCr 4+ crystal have been measured at 85 and 300 K in the range 10,000-37,500 cm -1 . The spectra have been interpreted by the use of crystal field theory for the states of the 3d 2 configuration acted on by a potential of predominantly T d symmetry. Fundamental details of the spectra, especially of the circular-dichroism spectra, are accounted for by contributions from the field of low symmetry C 1 , and spin-orbit interactions in the intensities of the electronic transitions of the Cr 4+ ion.

In this paper, the absorption spectrum of PbWO 4 :Cr 3+ crystals is measured at room temperature in the wavelength range from 340 to 520 nm. The d-d transitions of Cr 3+ ions in PbWO 4 crystals with tetragonal symmetry are calculated by the crystal-field theory. The theoretical results are in good a
