Popis:	In this paper we introduce a new model describing the coupling of 2 E and 4 Τ2 states of octahedrally coordinated Cr3+ ion, which includes spin-orbit and electron-lattice interactions and takes into account the electronic structure of both states. The model is used to calculate doublet lifetime. We have applied this model to the series of Cr3+ doped garnets characterized by the varying crystal field parameter 10 Dq and Oh symmetry of the Cr site and to the kyanite (A1203:SiO2), which is the case of different Cr3+ sites in one material, characterized by the relatively large component of the low symmetry crystal field. The agreement with experinient is reasonable.
