摘要/Abstract

摘要： 本文报道了一种测角单晶NMR探头。该探头采用单线圃双调谐电路,工作频率在90MHz-110 MHz连续可调,可进行交叉极化大功率去耦实验。文中提出了一种简单而有效的测角装置,可使单晶绕三个互相垂直轴转动实现单晶的NMR测量。作为典型的应用例子,本文利用该探头实现了单晶DGO(2NH₂CH₂COOH·H₂C₂O₄)屏蔽张量的测量。

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.
