We present the results of experimental investigations of the temperature behaviour of the magnetic resonance parameters in 'linear' and nonlinear regimes. The line shape of the microwave absorption and form of potential as a function of the magnetic moment deviation of the copper subsystem from the ...
According to the actual pH of AMD, the effects of different pH (2–4) on the adsorption process of Cu2+, Zn2+and Pb2+by lignite and MML were studied as shown in Fig.1a,b. With the increase of pH value, the adsorption of Cu2+, Zn2+and Pb2+by lignite and MML gradually increas...
al.80reported a study on Raman scattering at temperatures above and below the magnetic ordering temperature of 149 K. To date, the structures of [NH3(CH2)nNH3]ZnCl4(n = 2, 3, 4, 5, and 6) have been reported by X-ray diffraction analysis60,81,82,83. Finally, in the case ofM...
The [(H3N–(CH2)6–NH3)]2+ cations are accommodated between the chains as counter cations. The hexane-1,6-diammonium cations adopt a partial synclinal conformation. The chains are connected by strong and weak hydrogen bonds. Magnetic measurements reveal a paramagnetic Curie-Weiss behavior and ...

Also, the magnetic moment values in the range 1.22–1.45 BM for the copper (II) complexes 25–30 are of indicative anti-ferromagnetic spin-spin interaction through molecular association [40]. Complex 31 is diamagnetic and the central Ni2+ ion is in a square planar environment [40]. 2.1.4...
The following factors are considered; 63Cu:65Cu = 69.09:30.91; nuclear magnetic moment βn = 2.2206 (63Cu) and 2.3790 (65Cu); 14N (I = 1, 99.635%). In the meantime, 33S (I = 3/2, 0.74%), 13S (I = 1/2, 1.108%) and 15N (I = 1/2, 0.365%) are ignored. Next, we ...
