Dynamic Nuclear Polarization Enhancement of 200 at 21.15 T Enabled by 65 kHz Magic Angle Spinning

David Lyndon Emsley, Yu Rao, Moreno Lelli, Pierrick Berruyer, Gabriele Stevanato, Snaedis Björgvinsdóttir, Andrea Bertarello

Solid-state nuclear magnetic resonance under magic angle spinning (MAS) enhanced with dynamic nuclear polarization (DNP) is a powerful approach to characterize many important classes of materials, allowing access to previously inaccessible structural and d ...

Gadolinium(III) complexes have recently been demonstrated to have potential as polarizing agents for high-field dynamic nuclear polarization (DNP) NMR spectroscopy. By tailoring the ligand design to reduce the zero-field splitting (ZFS), we demonstrate a q ...

Nuclear magnetic resonance spectroscopy (NMR) can provide a great deal of information about structure and dynamics of biomolecules. The quality of an NMR structure strongly depends on the number of experimental observables and on their accurate conversion ...

Optimal pathway reconstruction on 3D NMR maps

Dominique de Werra

A three-dimensional Nuclear Magnetic Resonance (NMR) map displays the results of NMR experiments, that allow to determine the shape of a biological molecule. Shape calculation starts from a reconstruction of a sequence of NMR signals, which is equivalent t ...

Procédé de spectroscopie RMN avec dégradations d'induction prolongée de cohérences aux temps de vie longs

Geoffrey Bodenhausen, Aurélien Bornet, Sami Jannin

A Method for nuclear magnetic resonance (NMR) spectroscopy of a sample comprising the following steps: (a) excitation of long lived coherences (LLC) between the singlet state So and the central triplet state To of nuclei of the sample by initiating irradia ...

Dynamic Nuclear Polarization Enhanced NMR Spectroscopy for Pharmaceutical Formulations

David Lyndon Emsley, Aaron James Rossini, Moreno Lelli

Dynamic nuclear polarization (DNP) enhanced solid-state NMR spectroscopy at 9.4 T is demonstrated for the detailed atomic-level characterization of commercial pharmaceutical formulations. To enable DNP experiments without major modifications of the formula ...

A method for nuclear magnetic resonance (NMR) spectroscopy of a sample comprises preparation of the sample and carrying out an NMR spectroscopy measurement. Preparation includes excitation of long lived coherences (LLC) between the singlet state S0 and the ...

2013

Nuclear magnetic resonance (NMR) was discovered in the first half of the 20th century. Today, neither analytical chemistry without NMR spectroscopy nor medical diagnostics without magnetic resonance imaging (MRI) could be imagined. A magnetic resonance sig ...

Dynamic Studies through Control of Relaxation in NMR Spectroscopy

Nicola Salvi

In numerous biological processes that constitute the base of living organisms, protein function is fundamentally related to internal dynamics occurring on μs-ms time scales that can give rise to chemical exchange contributions to relaxation. In a heteronuc ...

EPFL2013

Relaxation processes induced by the antisymmetric part of the chemical shift anisotropy tensor (henceforth called anti-CSA) are usually neglected in NMR relaxation studies. It is shown here that anti-CSA components contribute to longitudinal relaxation rat ...
