Abstract
EPR spectra of polycrystalline compounds MnSO4.(NH4)2SO4.6 H2O, Gd2(SO 4)3.8 H2O, and NH4Fe(SO4)2.12 H2O are recorded at X-band and room temp erature. For the first two compounds, good agreement with simulated sp ectra of Gaussian lineshape is found, and the numerical values of the fine (D) and hyperfine (A) structure constants are obtained by fitting with experimental spectra. For the last compound, the fine structure characteristic of the cubic term (a) is responsible for the ''hyper-Ga ussian'' shape of the EPR line.
