Short summary

We have recently demonstrated the capability to rapidly spin spherical rotors inclined precisely at the magic angle (54.74°) with respect to the external magnetic field used for nuclear magnetic resonance (NMR) experiments. We show that it is possible to spin a spherical rotor without using turbine grooves and that these rotors are extremely stable because of the inherent spherical-ring geometry. These results portend the facile implementation of spherical rotors for solid-state NMR experiments.
