The NMR spectra of paramagnetic substances can feature shifts over thousands of ppm. In high magnetic field instruments, this corresponds to extreme offsets, which make it challenging or impossible to achieve uniform excitation without phase distortion. Furthermore, because of the intrinsic presence of a dead time during which spins freely evolve, a further phase distortion occurs. A decade ago, a processing approach based on the analysis of the statistics of the phase of the spectrum was… Expand

Observability of Paramagnetic NMR Signals at over 10 000 ppm Chemical Shifts
Detailed spin dynamics simulations indicate that, even with relatively slow electron spin relaxation, it remains possible to observe NMR signals of directly metal‐bonded atoms because pronounced rhombicity in the electron zero‐field splitting reduces nuclear paramagnetic relaxation enhancement.

Magic angle spinning NMR of paramagnetic proteins.
Metal ions are ubiquitous in biochemical and cellular processes. Since many metal ions are paramagnetic due to the presence of unpaired electrons, paramagnetic molecules are an important class ofExpand

What are the methodological and theoretical prospects for paramagnetic NMR in structural biology? A glimpse into the crystal ball.
It is predicted that further theoretical/computational improvements will essentially confirm the validity of the old semi-empirical equations for the analysis of the experimental paramagnetic data. Expand
A high-resolution view of the coordination environment in a paramagnetic metalloprotein from its magnetic properties.
It is shown that it is possible to determine the coordination environment of the paramagnetic metal in the protein at a resolution  inaccessible to other techniques. Expand
How the Ligand Field in Lanthanide Coordination Complexes Determines Magnetic Susceptibility Anisotropy, Paramagnetic NMR Shift, and Relaxation Behavior
This work examines recent progress in the theory of paramagnetic chemical shift and relaxation enhancement, where some long-neglected effects of zero-field splitting, magnetic susceptibility anisotropy, and spatial distribution of lanthanide tags have been accommodated in an elegant way. Expand
Taking Solution Proton NMR to Its Extreme: Prediction and Detection of a Hydride Resonance in an Intermediate-Spin Iron Complex.
The first detection of a metal-bonded hydrogen atom by solution NMR in a complex with a paramagnetic ground state illustrates the interplay of theory and experiment for the characterization of key components in paramagnetic base metal catalysis. Expand
Ligand-Field Energy Splitting in Lanthanide-Based Single-Molecule Magnets by NMR Spectroscopy.
The application of this NMR-based approach in an isostructural series of anionic lanthanide bis(cyclooctatetraenide) double-decker compounds bearing large rigid substituents is demonstrated, showing that the experimental method for determination of the LF parameters is an ideal complementation to other theoretical and experimental methods.

Metal centers in biomolecular solid-state NMR.
This review will give an overview of the properties of different paramagnetic centers and how they can be used to increase the chances of experimental success by solid state NMR. Expand
The Effects of Finite Rectangular Pulses in NMR: Phase and Intensity Distortions for a Spin-1/2
Pulses in NMR spectrometers have a finite length, but the usual hard- pulse assumption ignores it, and treats the pulse as a rotation of the frame of reference about the direction of theExpand
