In this paper, EPR study of the effective Hamiltonian parameters of the spectra of Cu2+:Cd2(NH4)2(SO4)3.6H2O single crystals has been carried out at different temperatures. The results show that this system exhibits JT effect, isotropy (T?122 K) and anisotropy (T<122 K) in the g-factor and hyperfine tensor (A) components in the (100) direction. The decrease in the g and A values with increasing temperature is similar to several known JT systems except the effective Hamiltonian parameter
