Abstract: A spinning apparatus for conducting magnetic resonance spectroscopy on a sample, having: an inner holder for the sample; mechanism for spinning the inner holder, while positioned in a magnetic field, about its axis; and a substantially nonmagnetic mechanical first bearing for supporting the first end-portion of the inner holder. Also, a spinning apparatus having: an inner holder for the sample; mechanism for spinning the inner holder, while positioned in a magnetic field, about its axis; a first and second bearing for supporting, respectively, a first and second end-portion of the inner holder; an outer housing for retaining the inner holder; mechanism for spinning the outer housing about its axis; and a substantially nonmagnetic mechanical third bearing for supporting the right end-portion of the outer housing. Also included is a device for measuring the magnetic resonance spectrum of a sample.
