THE OPTICAL SPECTRUM OF Co$sup 2+$ IN THE CUBIC CRYSTALLINE FIELD OF CaF$sub 2$. Technical Note No. 4
The optical spectrum of Co/sup 2+/ in CaF/sub 2/ is analyzed. Absorption bands are found at 3, 1.5, and 0.55 mu . These bands show fine structure. In addition, there are weak and narrower bands at 19,220, 19,580, 20,450, 21,750, 22,000, and 25,750 cm/sup -1/ and iatense lines at 44,250 and 48,200 cm/sup -1/. The spectrum is interpreted to arise from transitions from the orbital singlet to various Stark levels split by spin-orbit isteraction, and yields values of Dq =340 plus or minus 10 cm/sup -1/, E(P)=l4,OOO plus or minus lOO cm/sup -1/, and E(G) = 16,250 plus or minus 100 cm/sup -1/. The spectrum of Co/sup 2+/ in the eight coordinated cubic symmetry is compared with Co/sup 2+/ in octahedral and tetrahedral symmetry as well as with Cr/sup 3+/ in octahedral symmetry. (auth)
