Electron paramagnetic resonance of Gd 3+ in Eu 2 Zn 3 (NO 3 ) 12 ·24H 2 O single crystals is studied at ≈9.45 GHz and at 298 and 77 K. Gd 3+ substitutes for the Eu 3+ 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 b 2 0 .
