Coherence transfer between spy nuclei and nitrogen-14 in solids

Coherence transfer from ‘spy nuclei’ such as 1H or 13C (S = 1/2) was used to excite single- or double-quantum coherences of 14N nuclei (I = 1) while the S spins were aligned along the static field, in the manner of heteronuclear single-quantum correlation ...

Dynamics of silica-supported catalysts determined by combining solid-state NMR spectroscopy and DFT calculations

Frédéric Blanc, David Lyndon Emsley

The molecular dynamics of a series of organometallic complexes covalently bound to amorphous silica surfaces is determined experimentally using solid-state nuclear magnetic resonance (NMR) spectroscopy and density functional theory calculations (DFT). The ...

Improving resolution in proton solid-state NMR by removing nitrogen-14 residual dipolar broadening

David Lyndon Emsley

Residual dipolar coupling between quadrupolar and other nuclei under MAS has not usually been thought to be important in high field NMR spectroscopy. We show that coupling to (14)N broadens (1)H lineshapes significantly even at 11.7 T, and that we can deco ...

Spatially encoded strategies in the execution of biomolecular-oriented 3D NMR experiments

Mor-Miri Mishkovsky

Three-dimensional nuclear magnetic resonance (3D NMR) provides one of the foremost analytical tools available for the elucidation of biomolecular structure, function and dynamics. Executing a 3D NMR experiment generally involves scanning a series of time-d ...

Selective NMR measurements of homonuclear scalar couplings in isotopically enriched solids

David Lyndon Emsley, Bradley Floyd Chmelka

Scalar (J) couplings in solid-state NMR spectroscopy are sensitive to covalent through-bond interactions that make them informative structural probes for a wide range of complex materials. Until now, however, they have been generally unsuitable for use in ...

Proton to carbon-13 INEPT in solid-state NMR spectroscopy

David Lyndon Emsley

A refocused INEPT through-bond coherence transfer technique is demonstrated for NMR of rigid organic solids and is shown to provide a valuable building block for the development of NMR correlation experiments in biological solids. The use of efficient prot ...

Kinetics of photoinduced RNA refolding by real-time NMR spectroscopy

Philipp Wenter

By introducing a photolabile group in the Watson-Crick base-pairing site of a guanosine residue, a bistable 20-base RNA sequence was forced into a less stable conformation. A single laser pulse released the native sequence, and the subsequent refolding equ ...

Multiple refocusing in NMR spectroscopy: Compensation of pulse imperfections by scalar couplings

Geoffrey Bodenhausen

When applying multiple refocusing pulses to characterize the cross-correlated relaxation of heteronuclear multiple quantum coherence 2NxHx in biomols., the unavoidable effects of pulse imperfections are compensated by the scalar couplings between nitrogen ...

Toward dynamic isotopomer analysis in the rat brain in vivo: automatic quantitation of 13C NMR spectra using LCModel

Rolf Gruetter

The LCModel method was adapted to analyze localized in vivo (13)C NMR spectra obtained from the rat brain in vivo at 9.4 T. Prior knowledge of chemical-shifts, J-coupling constants and J-evolution was included in the analysis. Up to 50 different isotopomer ...

High-Q factor RF planar microcoils for micro-scale NMR spectroscopy

Giovanni Boero, Radivoje Popovic, Pierre-André Besse, Franck Vincent, Charles Massin

We present the design, fabrication and test of high-Q factor radiofrequency planar microcoils for nuclear magnetic resonance (NMR) spectroscopy in small volume samples. The coils are fabricated on glass wafers using high-aspect ratio SU-8 photoepoxy and co ...
