Abstract
The strong features in the absorption spectrum and the laser excited fluorescence spectrum have been interpreted as arising from levels of Pr3+ in the D2d symmetry site of ThBr4. 43 energy levels have been fitted to the parameters with an rms deviation of 61 cm−1. The values of the crystal field parameters are B20=260.0, B40=−644.2, B44=929.2, B60=1089.0 , and B64=240.6 cm−1. The presence of other crystal symmetry sites is observed.
