Abstract: We presented a NMR probe for single crystal measurements in the article. The probe employed a single coil double tuned both for proton and a heteronucleus, whose resonant frequencies covered a range from 90MHz to 110MHz, therefore it could perform crosspolarization (CP) experiments associated with high power proton decoupling. A simple but effective goniometer mechanism ensured the sample to rotate precisely about the three axes which were orthogonal with one another. This probe was applied for the measurements of chemical shift tensors in single crystals. We also presented, for an example, the results for DGO (2NH₂CH₂COOH. H₂C₂O₄)in the work.

Key words: single coil double tuned NMR probe, Goniometer, Chemical shift tensors
