Abstract. Magic angle spinning averages out the dipolar coupling among spins in rigid solids, as well as other sources of magnetic inhomogeneity, leading to sideband suppression. To achieve line widths close to that achievable for the liquid state, it has been postulated that 250 kHz rotation frequencies have to be exceeded. Here we explore a perspective for a research project to achieve this goal.

The magic angle spinning (MAS) technique of solid state NMR requires samples to be rapidly rotated within a magnetic field. The rotation rate speed record is 150 kHz, or 9 million RPM, and hence MAS turbines hold the world rotation speed record for extended objects. The containers holding the samples are made of the strongest materials known, to be able to withstand the excessive centrifugal forces. To overcome the speed limit, this paper delineates a way to do so using an optical tweezers setup
