Isotropic Hyperfine Interaction

The experimental 14N and 17O n.m.r, results in a series of lanthanide complexes are successfully interpreted from a second-order perturbation treatment of the calculation of (S2), where bonding effects and spin-orbit coupling mixing are incorporated. The isotropic hyperfine interaction constants are shown to be negative for 14N and positive for 17O but both independent of the particular lanthanide ion. We also confirm that the 4f orbitals are not involved in direct bonding with the ligands.

Metal Dithiocarbamates

From a study of the isotropic proton hyperfine interaction constants for a series of metal dithiocarbamates, and their redox behaviour, it is shown that for iron(111) and manganese(111) dithiocarbamates there is a simple relationship between E1/2 and the NCH2 proton hyperfine interaction constant in the 6Al state. Hence the redox process for these compounds is inferred to take place through the nitrogen atom.

The paramagnetic resonance of Fe3+-ions in cubic synthetic ZnS crystals has been observed after uv-irradiation at 77 °K. The spectrum was analysed withg=2.0194 ± 0.0003 and |α |=0.0128 ± 0.0001 cm-1,where 3 α is the zero-field splitting. The hyperfine interaction constant of the 2.2% isotope Fe57 was found to be |A|= 0.00078 ± 0.00005 cm-1. The splitting of the central fine structure line revealed the existence of submicroscopic twins. Two additional epr-lines have been observed after crushing and after annealing the crystals in zinc vapour.
