Paramagnetic Cobalt(III) Complexes with Organic Ligands. VIII. The NMR Spectra of Paramagnetic Tetraammine(5-nitrosalicylato)cobalt(III) Chloride Nitrate Hydrate and the Related Compounds

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 ...

the evaluation of language related engagment and task related engagment with the purpose of investigating the effect of metatalk and task typology

abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...

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...

NMR of paramagnetic proteins

Paramagnetic dithiolene complexes as metallo-ligands: ether/thioether coordination.

The secondary coordination ability of a paramagnetic nickel dithiolene complex, bearing an ether coordinating function within a nine-membered flexible ring, has been demonstrated in its [NiCl(DMF)(2)](+) complex, through coordination by both ether and thioether functions, allowing for a ferromagnetic interaction between both paramagnetic entities.
