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...

Predicting the spin state of paramagnetic iron complexes by DFT calculation of proton NMR spectra.

Many transition-metal complexes easily change their spin state S in response to external perturbations (spin crossover). Determining such states and their dynamics can play a central role in the understanding of useful properties such as molecular magnetism or catalytic behavior, but is often far from straightforward. In this work we demonstrate that, at a moderate computational cost, density f...

Analytical Applications of NMR Spectra in the Gas Phase

Gas-phase multinuclear magnetic resonance (MR) spectra allow the total elimination of intermolecular effects from magnetic shielding in molecules. Consequently, the resonance frequencies of isolated atoms and molecules are also available for reading from MR spectra. Following the connectivity between nuclear magnetic moments, resonance frequencies of two different nuclei in the same MR experime...

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 ...
