Good Agreement

The preparation of completely clear bromoelpasolites Cs2NaLnBr6 is described. The particular suitability of the resulting products for spectroscopical measurements is demonstrated by the electronic Raman spectrum of Cs2NaPrBr6. Using the crystal field parameter set B40 = 232 and B60 = 17 cm-1 a good agreement between observed and calculated signals could be achieved.

Considering the crystal field parameter Dq and average covalent factor N, the energy levels of NaMg3Al(MoO4)5: Cr3+ crystal at 295 K are calculated by diagonalizing the energy matrix of 3d3. At low temperature 9 K the bond length of Mg-O is calculated by adjusting the value to fit the spectra of Mg site. The value of Mg-O bond length is 2.0528 Å. The equation relationship of Mg-O between bond length and temperature is achieved.The calculated values are consistent with the experimental spectra.
