The Study of Electronic Spectrum of Mn²⁺ Ion in System KMgF₃: Mn²⁺

On the basis or the SCCF model, the complete energy matrices of O_h^* double group for spin quartet states of d⁵ system have been formulated. The energy levels of d-d transistion of Mn²⁺ in KMgF₃:Mn²⁺ are calculated with these matrices. Calculted resultes are good agreement with experment observation. The splitting of energy level between ⁴A_1g (G) and ⁴E_g(G) is orginated from spin-correlation effection; three absorption bands (38715cm^-1, 40650cm^-1, 43860cm^-1) can be assigned in our model; some bands which can't be explained by the SCCF model have been explained with our calculated results.
