Electron paramagnetic resonance of Gd³⁺ in Eu₂Zn₃(NO₃)₁₂^.24H₂O single crystals is studied at ĄÖ 9.45 GHz and at 298 and 77 K. Gd³⁺ substitutes for the Eu³⁺ site. In addition to the allowed fine structure lines, forbidden transitions (ΔM= ∓2,∓3,∓4,∓5) are observed. The superposition model is applied to the zero-field splitting parameter b₂⁰.
