Solid-state NMR spectrometer, sample holder therefor, and method of solid-state NMR spectroscopy

摘要

A high-resolution solid-state NMR spectrometer which can measure a disklike sample. The spectrometer includes: a stator having an air bearing disposed within the static magnetic field, the rotor being disposed in the stator; and an engaging mechanism mounted in a one-end portion of the rotor and detachably holding a sample holder that holds the disklike sample.

主权项

1. A solid-state NMR spectrometer for obtaining a solid-state NMR spectrum by directing RE excitation pulses to a sample from a transmit coil while spinning a rotor at high speed about an axis tilted at a magic angle of about 54.7° to a static magnetic field, said spectrometer comprising:
a rotor having a concave bore; a disklike sample-holding portion permitting a sample to be placed on its surface or received in an internal cavity formed in the sample-holding portion and a convex pillar portion mounted on a central portion of a rear surface of the disklike sample-holding portion, and wherein the sample-holding portion is mounted to an end portion of the rotor by the convex pillar portion inserted in the concave bore of the rotor; a stator having an air bearing placed within the static magnetic field, the rotor being disposed in the stator; and an engaging mechanism detachably holding said sample-holding portion.
