| Abstract: | The absorption spectrum of Ni2+ doped in Cs2Mg(SO4)2 · 6H2O single crystals has been studied at room and liquid nitrogen temperatures in the range 7000–34000 cm?1. The observed spectrum is satisfactorily interpreted in terms of cubic ligand field model including spin-orbit coulping. The ligand field parameters evaluated to best fit the observed spectrum are B = 955 cm?1, C = 3572 cm?1, Dq = 910 cm?1 and ξ = 550 cm?1. The non-ligand field band observed at 77K has been interpreted to be the superposition of vabrational mode of SO42? radical on 3T1g(F) band. |
