Broadband Heteronuclear Spin Decoupling in Solids

چکیده
While heteronuclear broadband decoupling by composite pulse sequences is a well established method in isotropic liquids [ l-41, analogous decoupling sequences for oriented systems have been introduced only recently [ 5-91. Those sequences [ 891, termed COMARO, were derived from a theoretical analysis of heteronuclear decoupling in the presence of homonuclear interactions like dipole-dipole and quadrupole interactions via computer simulations for various spin systems. The sequences consist of phaseshifted composite 90” pulses that are compensated for off-resonance effects. The sequence which was used in the experiments described in this paper is

Broadband Heteronuclear Decoupling in the Presence of Homonuclear Dipolar and Quadrupolar Interactions
A new family of composite decoupling sequences designed for heteronuclear broadband decoupling of spin-l and spin-f in solids and liquid crystals is introduced. The pulse sequences are windowless and perform net rotations in spin space about magic-angle axes. Computer simulations and experimental results are presented to demonstrate their decoupling performance and to discuss their susceptibili...
متن کاملDipolar Recoupling and Decoupling
In solid state nuclear magnetic resonance spectroscopy, the magic angle spinning technique is often used to remove anisotropic interactions and generate high resolution spectra. However, these interactions contain valuable information about molecular structure and dynamics. In particular, the dipole-dipole coupling strength between two spin-1/2 nuclei is a direct reflection of their interatomic...
متن کاملSimulating spin dynamics in organic solids under heteronuclear decoupling.
Although considerable progress has been made in simulating the dynamics of multiple coupled nuclear spins, predicting the evolution of nuclear magnetisation in the presence of radio-frequency decoupling remains challenging. We use exact numerical simulations of the spin dynamics under simultaneous magic-angle spinning and RF decoupling to determine the extent to which numerical simulations can ...
متن کاملRationalising Heteronuclear Decoupling in Refocussing Applications of Solid‐State NMR Spectroscopy
Factors affecting the performance of 1 H heteronuclear decoupling sequences for magic-angle spinning (MAS) NMR spectroscopy of organic solids are explored, as observed by time constants for the decay of nuclear magnetisation under a spin-echo (T2' ). By using a common protocol over a wide range of experimental conditions, including very high magnetic fields and very high radio-frequency (RF) nu...

We recently noted [R. K. Harris, P. Hodgkinson, V. Zorin, J.-N. Dumez, B. Elena, L. Emsley, E. Salager, and R. Stein, Magn. Reson. Chem. 48, S103 (2010)] anomalous shifts in apparent (1)H chemical shifts in experiments using (1)H homonuclear decoupling sequences to acquire high-resolution (1)H NMR spectra for organic solids under magic-angle spinning (MAS).
