The electronic ground state wave functions in FeCO<SUB>3</SUB> and FeTiO<SUB>3</SUB> are deduced from the nuclear quadrupole coupling data. With these wave functions, the contribution of the intra atomic magnetic dipolar interaction and that of the electron orbital current effect to the internal magnetic field are calculated. A similar analysis is done also on FeF<SUB>2</SUB>. The magnitude of the Fermi interaction, which is obtained by subtracting the above mentioned contributions from the observed value of the internal magnetic field, shows a reasonable dependence on the electronegativity of negative ion. Also the energy separations of the crystalline field levels in FeF<SUB>2</SUB> are calculated by use of the Mössbauer data and the data of the paramagnetic resonance experiment on Fe<SUP>2+</SUP> in ZnF<SUB>2</SUB>.
