Nmr Studies of Paramagnetic Molecules

In this paper a résumé is given on nmr studies of paramagnetic molecules with specific reference to manganic and ferric dithiocarbamates. The temperature dependence of these spectra is discussed, and the isotropic proton hyperfine interaction constants are examined, yielding information about the electronic configuration in these molecules. The nmr results are complemented by magnetic susceptib...

1H NMR techniques in studies of transport of paramagnetic ions in multicellular systems.

Two different pulse sequences used in 1H NMR spectroscopy termed free induction decay amplitude recovery (FIDAR) and spin-echo recovery (SER) were applied to studies of transport of paramagnetic ions in multicellular systems. The molar relaxivity of several paramagnetic species (Fe3+, Co2+, Ni2+, Cu2+, Mn2+, MnEDTA2-, dextran-magnetite) in water solutions was measured at 32 MHz resonance freque...

NMR Spectroscopy of Paramagnetic Complexes Part 39*-Natural Abundance *H NMR of Paramagnetic Sandwich Compounds

The methylated metallocenes (MeCp),M with M = V, Cr, Mn, Co, Ni (1-5) were investigated by 'H and 'H NMR spectroscopy at natural abundance. The 2H NMR signals are narrower by a factor of up to 30 compared with the corresponding 'H NMR signals, thus establishing an inexpensive method and a general improvement of the NMR spectra of paramagnetic x-complexes. This has allowed the resolution of the ...

Solution structure of the paramagnetic complex of the N-terminal domain of calmodulin with two Ce3+ ions by 1H NMR.

The solution structure of the dicerium(III) complex of the N-terminal domain of calmodulin (Ce2-TR1C hereafter) has been solved employing paramagnetic T1 relaxation enhancements and pseudocontact shifts introduced by the Ce3+ ions, together with conventional NOE constraints. The use of pseudocontact shift constraints constitutes the first attempt to locate metal ions within a protein structure ...
