“…2͑C͒. In both orientations one finds a behavior typical of one-dimensional systems showing a broad maximum around T Ϸ 28 K that can be nicely described by the Bonner-Fisher model as documented by a corresponding fit 30 depicted as solid black and grey lines for H ʈ b and H Ќ b, respectively. The deduced exchange coupling constants J NMR / k B are given in Table I and again confirm the values from the bulk susceptibility.…”

“…For both orientations the lineshift K͑T͒ nicely follows the Bonner-Fisher-type behavior 29 for the bulk susceptibility bulk ͑T͒ of an antiferromagnetic spin chain as indicated by the solid line. This line is a fit using the rational function given by Estes et al 30 The coupling constants J NMR / k B deduced from these fits are summarized in Table I for 7 Li NMR for comparison with the respective values of the bulk susceptibility. We note that the strong anisotropy of the 7 Li lineshift seems to be intimately connected with the crystallographic arrangement of the Li + ions on nonmagnetic chains.…”

NMR measurements were performed on single-crystalline samples of the one-dimensional Heisenberg antiferromagnet ͑1D HAF͒ LiCuVO 4 . We investigated 7 Li and 51 V NMR spectra, deduced the respective lineshifts K͑T͒, spin-lattice relaxation rates 1 / T 1 , and spin-spin relaxation rates 1 / T 2 and 1 / T 2G . The results are compared to theoretical predictions for the relaxation rates 1 / T 1 ͑T͒ and 1 / T 2G ͑T͒ deduced from the dynamic susceptibility ͑q , ͒ of a 1D HAF spin chain as proposed by Sachdev ͓Phys. Rev. B 50, 13006 ͑1994͔͒. We document a correspondence between the anisotropic relaxation rates derived from electron paramagnetic resonance linewidth ⌬H͑T͒ and nuclear magnetic resonance 1 / T 1 ͑T͒, respectively, the former being well described in the framework of symmetric anisotropic exchange interactions for LiCuVO 4 by Krug von Nidda et al. ͓Phys. Rev. B 65, 134445 ͑2002͔͒.

“…accordance with the fact that chelation increases the activity. e chelation reduces the polarity [24,25] of the metal ion, mainly, because of the partial sharing of its positive charge with the donor groups and possibly the -electron delocalization within the whole chelate ring [26][27][28]. is process of chelation thus increases the lipophilic nature of the central metal atom, which in turn favours its permeation through the lipid layer of the membrane [29][30][31].…”

Some new coordination compounds of palladium(II) have been synthesized by the reaction of palladium(II) acetate with azomethines in a 1 : 2 molar ratio using acetonitrile as a reaction medium. Azomethines used in these studies have been prepared by the condensation of 2-acetyl �uorene and 4-acetyl biphenyl with glycine, alanine, valine, and leucine in methanol. An attempt has been made to probe their bonding and structures on the basis of elemental analyses and IR, 1 H, and 13 C NMR spectral studies. Pd(II) compounds have been found to be more active than their uncomplexed ligands as both of them were screened for antibacterial, antifungal, and insecticidal activities.
