The mode of coordination of8 manganese(fI), cobaltm, nickel(H), copper(II), zinc(H), lead(II) and cadmium(I1) to sodium ascorbate (NaHAsc) was investigated using IR, UV-visible, AAS, elemental microanalyzer, conductivity, magnetic and 'M and I3C NMR spectroscopic studies, NaNAsc is bidentate and coordination was through the carbonyl group and the oxygen atom of carbon-2 enolic hydfoxyl grou...

the mode of coordination of8 manganese(fi), cobaltm, nickel(h), copper(ii), zinc(h), lead(ii) and cadmium(i1) to sodium ascorbate (nahasc) was investigated using ir, uv-visible, aas, elemental microanalyzer, conductivity, magnetic and 'm and i3c nmr spectroscopic studies, nanasc is bidentate and coordination was through the carbonyl group and the oxygen atom of carbon-2 enolic hydfoxyl gro...

using hartree-fock su-sheriffer-heeger (hf-ssh) model, we have studied the dependence of the energies of the ground (magnetic triplet state) and the first exited (nonmagnetic singlet state) states of the size-2 trigonal zigzag graphene nanoflake (size-2 nf) on the intensity of an external in plane static electric field at zero temperature. we identify a transition from the magnetic triplet stat...
