Apparatus and Method for Performing NMR Spectroscopy on Solid Sample.

摘要

Nuclear magnetic resonance analysis of powdery or other randomly oriented solid samples is improved by slowly rotating the sample with a period exceeding the nuclear spin relaxation time of nuclei in the sample. As a result, a relatively large proportion of the crystallites in the sample are brought into resonance, thereby improving the signal to noise ratio of the NMR reading. In addition, information about the width of the entire spectrum can be obtained from analysis of measurements of only a portion of it.
