Kopsavilkums

In the present paper, we report on a systematic comparative study of the dynamic ⁴T_2g⊗e_g Jahn-Teller effect for the Cr³⁺ ion in several elpasolite crystals (Cs₂NaInCl₆, Cs₂NaYCl₆, Cs₂NaScCl₆, Cs₂NaYF₆, Cs₂NaYBr₆, and K₂NaScF₆). Based on the available in the literature data on the frequencies of normal vibrations and Huang-Rhys parameters, we estimate the force constants, magnitudes of the normal modes displacements, changes in the chemical bond lengths and Jahn-Teller stabilization energy for all above mentioned systems. Several trends in the obtained results are revealed and analyzed.
