Recently, proton-detected magic-angle spinning (MAS) solid-state nuclear magnetic resonance (NMR) spectroscopy has become an attractive tool to study the structure and dynamics of insoluble proteins at atomic resolution. The sensitivity of the employed multidimensional experiments can be systematically improved when both transversal components of the magnetization are transferred simultaneously after an evolution period. The method of preservation of equivalent pathways has been explored in...

Solid state NMR of proteins at high MAS frequencies: symmetry-based mixing and simultaneous acquisition of chemical shift correlation spectra
Solid state NMR of proteins at high MAS frequencies: symmetry-based mixing and simultaneous acquisition of chemical shift correlation spectra
Abstract We have carried out chemical shift correlation experiments with symmetry-based mixing sequences at high MAS frequencies and examined different strategies to simultaneously acquire 3D correlation spectra that are commonly required in the structural studies of proteins. The potential of numerically optimised symmetry-based mixing sequences and the simultaneous recording of chemical shift correlation spectra such as: 3D NCAC and 3D NHH...

[NMR paper] Sensitivity enhancement in two-dimensional solid-state NMR spectroscopy by transverse
Sensitivity enhancement in two-dimensional solid-state NMR spectroscopy by transverse mixing.
Related Articles Sensitivity enhancement in two-dimensional solid-state NMR spectroscopy by transverse mixing.
Chemphyschem. 2004 Jun 21;5(6):863-8
Authors: Tycko R
The sensitivity of two-dimensional (2D) 13C-13C solid-state NMR spectroscopy under magic-angle spinning (MAS) is shown to be enhanced by the use of transverse polarization transfer in place of the conventional longitudinal polarization transfer. Experimental results are reported for 2D...

Transverse dephasing optimized solid-state NMR spectroscopy.

J Am Chem Soc. 2003 Nov 19;125(46):13938-9
Authors: De Paëpe G, Giraud N, Lesage A, Hodgkinson P, Böckmann A, Emsley L
It is shown how coherence lifetimes in solid-state NMR experiments can be controlled. New decoupling schemes are introduced which actively optimize dephasing times, providing increases of up to a factor of 2 with respect to the best existing schemes. The new schemes are implemented in...
