Scheme of HRMAS stator. The figure shows the disposition of both RF solenoid and gradient coils as well as indicates the inclination of rotation axis at the magic angle (θ = 54.7°) in respect of static magnetic field (B 0). During HRMAS acquisitions, each sample has to be spun at a moderate rate (ν R) around an axis inclined at the magic angle.
