Abstract
The present invention discloses a sample tube for the magic angle high-speed rotation method used in a solid nuclear magnetic resonance device probe wherein a radio wave irradiation/detection coil is disposed close to a sample and a method of measuring a high resolution nuclear magnetic resonance absorption spectrum using the same. This tube is suitable for solid nuclear magnetic resonance (solid NMR) measurements of minute amounts of sample. The sample tube has a capillary part filled with a sample and non-capillary parts situated at its two ends, and a spinner which can be detachably inserted into at least one of the outer ends of the non-capillary parts. The capillary part and non-capillary parts are made of a ceramic and/or polymer material.
