The Electron Spin Resonance of Mn 2+ in natural crystals of hemimorphite was studied at RT, X‐band. No fine structure other than the central M = | + 1/2 〉 ⇆ | −1/2 > transition with allowed (Δ m = 0) and forbidden (Δ m = ±1) hyperfine transitions were observed. The spectrum was fitted with the spin Hamiltonian parameters g = 2.001, A = −84.6 × 10 −4 cm −1 . The crystal field parameter D was estimated equal to (8 ± 2) × 10 −3 cm −1 . The most striking result is the size of the hyperfine splitting constant favoring occupancy of sixfold coordinated sites.
