Nuclear overhauser spectroscopy of chiral CHD methylene groups

Geoffrey Bodenhausen, Fabien Ferrage

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 ...

High-resolution NMR of hydrogen in organic solids by DNP enhanced natural abundance deuterium spectroscopy

David Lyndon Emsley, Aaron James Rossini, Judith Schlagnitweit

We demonstrate that high field (9.4T) dynamic nuclear polarization (DNP) at cryogenic (similar to 100 K) sample temperatures enables the rapid acquisition of natural abundance H-1-H-2 cross-polarization magic angle spinning (CPMAS) solid-state NMR spectra ...

Searching for optimal conditions during one- and multi-dimensional solid-state NMR experiments in high static fields may require spinning the sample at frequencies above 40 kHz. This implies challenging requirements for heteronuclear spin decoupling. We ha ...

Decoupling of Magnetic Resonance Signals in Time and Frequency Domain

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 ...

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 ...

Fast and shift-insensitive similarity comparisons of NMR using a tree-representation of spectra

Luc Patiny, Julien Wist

An efficient method to extract and store information from NMR spectra is proposed that is suitable for comparison and construction of a search engine. This method based on trees doesn't require any peak picking or any pre-treatment of the data and is found ...

Improving Sensitivity in Solid State NMR

Sensitivity in Nuclear Magnetic Resonance (NMR), especially in solid-state NMR, has always been a challenging and important issue and thus a motivation for new developments. The magnetic field B0, the gyromagnetic ratios of the observed nuclei, as well as ...

Extending Timescales and Narrowing Linewidths in NMR

Geoffrey Bodenhausen, Aurélien Bornet, Pascal Miéville, Sami Jannin, Diego Carnevale, Paul Romeo Vasos, Simone Ulzega, Marc Anthony Caporini, Nicola Salvi, Martial Rey

Among the different fields of research in nuclear magnetic resonance (NMR) which are currently investigated in the Laboratory of Biomolecular Magnetic Resonance (LRMB), two subjects that are closely related to each other are presented in this article. On t ...
