Abstract
Optical absorption spectrum of Co2+ doped rubidium zinc sulphate hexahydrate has been investigated both at room and at liquid nitrogen temperatures. The gross features of the observed spectrum are characteristic of octahedral symmetry associated with spin-orbit interaction. The interelectronic repulsion (B, C), crystal field (Dq) and spin-orbit (ζ) parameters which give a good fit to the observed band positions areB = 860 cm−1,C = 3870 cm−′,Dq = 980 cm−1,ζ= 500 cm−1. The non-ligand bands observed in the spectrum are attributed to vibrational modes of water molecule.
