Abstract : The report covers the work done on the optical and electron spin resonance properties of rare earth doped CdIn2S4 to determine the symmetry and crystal field parameters for the site occupied by the rare earth ion. Yb(3+) is used to show that the site occupied by the rare earth ion is dominantly cubic but with a small trigonal distortion along the <111> direction. The structure that gives the best fit to the experimental results as decided on a point charge model is Cd(1/2)In(1/2)(Cd(1/2)In(3/2))S4. The same crystal field found to be appropriate for Er(3+) with the cubic crystal field parameters A(4)<r to the 4th> = 195/cm and A(6)<r to the 6th> = 8/cm. (Author)
