ABSTRACT:
A probehead in a nuclear magnetic resonance spectrometer is disclosed. The probehead comprises a sample holder supporting a sample under investigation. The sample is spinned about a spinning axis. The sample holder is tilted with its spinning axis by an angle with respect to a probehead longitudinal axis. The longitudinal axis coincides with the principal direction of a surrounding constant magnetic field. A servo-mechanical actuator is provided for varying the angle. The actuator is driven by a force derived from the magnetic field.
