Positive residual maxima of different heights, deviating in shape considerably from the rotational cylindrical symmetry of σ-bond charge accumulations, were observed on the S – O bond lines of the [SO4]2− anions, revealing strong polarization effects from the Fe cations. No residual...
We report EPR measurements at 9.77 and 34.1 GHz in powder and single crystal samples of the ternary copper amino acid complex Cu(l-arginine)2(SO4)· (H2O)6. The single crystal Electron Paramagnetic Resonance spectra display a single resonance for all magnetic field orientations in the ca and...
