Explain why cyano or phosphine ligands are placed high in the spectrochemical series but the hydroxide ligand or the halo ligands are quite low in the spectrochemical series. Strong field ligands such as CN-: (a) usually produce high spin compl...
accompanied by the formation of two well-resolved lobes at the second shell (Fig.3e, f). This demonstrated that Cu(NH3)2+species are oxidized into CuIIions and that the interaction between the Cu2+ions and the zeolite framework is recovered. Besides the scattering by framework Si (or Al)...
ignava RNR, a series of assays was performed in which NrdA was mixed with NrdB∆169apo in combination with vary- ing amounts of M n2+ and/or F e2+ salts. As seen in Fig. 1a, the addition of Mn2+ to the assay had a strong activating effect. Close to maximum ...
In As and P heteroarenes, for X = NO2 there is a strong enhancement of the EA properties for the 2-substitution. Regarding the 4-derivatives, the NO2 is more EA than in the 3-derivatives, but only slightly. In the case of X = NH2, the amino group in the 2-derivatives is the ...
