On the quadrupole splitting in ferrous compounds
Chemical Physics Letters, 1969It is shown that the major contribution to the low temperature “saturation” value of the quadrupole splitting in ferrous compounds is independent (with a few well-defined exceptions) on the site symmetry of the Fe2+ ion. This explains the experimental fact that the measured values of this quantity in most compounds fall within ≈ 20% of each other.

Mössbauer Study of Magnetic Properties in Ferrous Compounds
Journal of the Physical Society of Japan, 1964Using the Mossbauer effect of Fe 57 , ferrous compounds have been investigated systematically in order to elucidate their magnetic properties from an atomic point of view. Parameters of isomer shifts, quadrupole interactions and internal magnetic fields at the iron nuclei at various temperatures are listed in Table I.

Electric-Field Gradient Tensor in Ferrous Compounds
Physical Review, 1964The electric-field gradient tensor at the iron nucleus in ferrous (${\mathrm{Fe}}^{2+}$) compounds is investigated. One sees that under the combined action of axial and rhombic crystalline fields and the spin-orbit interaction, the ferrous-ion $(^{5}D,3{d}^{6}){d}_{\ensuremath{\epsilon}}$ states produce a large, temperature-dependent, contribution to ...

The effect of ferrous sulfate (FeSO4) treatment on the removal of cyanide compounds and the improvement of biodegradability of coking wastewater were investigated by varying Fe:TCN molar ratios. Results suggested that the reaction between FeSO4 and coking wastewater was a two-step process.

The nitrosyl compounds of ferrous animal haloperoxidases
Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology, 1984Human myeloperoxidase, human eosinophil peroxidase and bovine lactoperoxidase (donor: hydrogen-peroxide oxidoreductase, EC 1.11.1.7) reduced with ascorbic acid form nitrosyl compounds which show rhombic EPR signals centered at g = 2. Using 14NO (IN = 1), the central resonance signal exhibited a hyperfine structure of nine lines originating from a ...

A Superoxo-Ferrous State in a Reduced Oxy-Ferrous Hemoprotein and Model Compounds
Journal of the American Chemical Society, 2003Cryoreduction of the [FeO2]6 (n = 6 is the number of electrons in 3d orbitals on Fe and pi* orbitals on O2) dioxygen-bound ferroheme through irradiation at 77 K generates an [FeO2]7 reduced oxy-heme. Numerous investigations have examined [FeO2]7 centers that have been characterized as peroxo-ferric centers, denoted [FeO2]per7, in which a ferriheme ...
