Abstract
Spectral resolution is key to unleash the structural and dynamic information contained in NMR spectra. Fast magic-angle spinning (MAS) has recently revolutionized the spectroscopy of biomolecular solids. We here report a further remarkable resolution improvement in the spectra of four fully protonated proteins and a small drug molecule, by pushing the MAS rotation frequency even higher, to 150 kHz, than the more routinely used 100 kHz. We observe a reduction of the average homogeneous linewidth by a factor 1.5 and a decrease in the observed linewidth by a factor 1.25. We conclude that even faster MAS is highly attractive and increases mass sensitivity at a moderate price in overall sensitivity.

Sensitivity and resolution of proton detected spectra of a deuterated protein at 40 and 60Â*kHz magic-angle-spinning
Abstract
The use of small rotors capable of very fast magic-angle spinning (MAS) in conjunction with proton dilution by perdeuteration and partial reprotonation at exchangeable sites has enabled the acquisition of resolved, proton detected, solid-state NMR spectra on samples of biological macromolecules. The ability to detect the high-gamma protons, instead of carbons or nitrogens, increases sensitivity. In order to achieve...
