Default Highly Stable Magic Angle Spinning Spherical Rotors Lacking Turbine Grooves

From The DNP-NMR Blog:

Highly Stable Magic Angle Spinning Spherical Rotors Lacking Turbine Grooves

Osborn Popp, Thomas M., Alexander Däpp, Chukun Gao, Pin-Hui Chen, Lauren E. Price, Nicholas H. Alaniva, and Alexander B. Barnes. “Highly Stable Magic Angle Spinning Spherical Rotors Lacking Turbine Grooves.” Preprint. Solid-state NMR/Instrumentation, April 1, 2020.


https://doi.org/10.5194/mr-2020-2.


The use of spherical rotors for magic angle spinning offers a number of advantages including improved sample exchange, efficient microwave coupling for dynamic nuclear polarization nuclear magnetic resonance (NMR) experiments and, most significantly, high frequency and stable spinning with minimal risk of rotor crash. Here we demonstrate the simple retrofitting of a commercial NMR probe with MAS spheres for solid-state NMR. We analyze a series of turbine groove 5 geometries to investigate the importance of the rotor surface on spinning performance. Of note, rotors lacking any surface modification spin rapidly and stably even without feedback control. The high stability of a spherical rotor about the magic angle is shown to be dependent on its inertia tensor rather than the presence of turbine grooves.

[NMR paper] Setting the magic angle for fast magic-angle spinning probes
Setting the magic angle for fast magic-angle spinning probes Publication date: Available online 15 June 2018 Source:Journal of Magnetic Resonance</br> Author(s): Susanne Penzel, Albert A. Smith, Matthias Ernst, Beat H. Meier</br> Fast magic-angle spinning, coupled with 1H detection is a powerful method to improve spectral resolution and signal to noise in solid-state NMR spectra. Commercial probes now provide spinning frequencies in excess of 100 kHz. Then, one has sufficient resolution in the 1H dimension to directly detect protons, which have a gyromagnetic...

Acc Chem Res. 2013 Mar 18; Authors: Knight MJ, Felli IC, Pierattelli R, Emsley L, Pintacuda G Abstract Metal ions are ubiquitous in biochemical and cellular processes. Since many metal ions are paramagnetic due to the presence of unpaired electrons, paramagnetic molecules are an important class of targets for research in structural biology and related fields. Today, NMR spectroscopy plays a central role in the...
