Large amount of X‐band EPR data, for external field orientations in both, the zx and xy planes, are obtained for Gd 3+ ion doped rare‐earth trichloride hexahydrate (RCH), rare‐earth trisulfate octahydrate (RSO), and rare‐earth trinitrate hexahydrate (RNH) single crystals. A rigorous least‐squares fitting procedure is used to evaluate the spin Hamiltonian parameters g ‖, g ⊥ and b l m(including those with negative m values). Approximate linear dependences upon the host rare‐earth ion radius is found on both, the parameters b 2 0and b 2 2within each family of the isostructural hosts investigated.
