1. A solid-state high-resolution two-dimensional (2D) NMR spectrometer was developed, which involves a cylindrical gas-bearing samplespinning system, a rotation-axis switching system, a VT CPMAS probe, a rotation speed stabilizer etc.2. <^(13)C> chemical shift tensors in <beta> -quinol-methanol clathrate were determined by using chemical-shift SASS 2D NMR.3. 2D-J NMR spectroscopy for rigid solids was developed, and applied to <beta> -quinol-methanol clathrate and p-dimethoxybenzene.4. The CH bond lengths in calcium formate were accurately determined by using dipolar SASS 2D NMR.5. Dynamic structures of molecules trapped in some clathrates were studied by using dipolar SASS 2D NMR.

1.研制了一种固态高分辨二维核磁共振谱仪，包括圆柱形气浮样品旋转系统、旋转轴切换系统、VT CPMAS探头、转速稳定器等.用<beta>化学位移SASS二维NMR测定了喹啉-甲醇包合物的&lt;^（13）C&gt;化学位移张量.建立了刚性固体的2D-J NMR谱，并将其应用于<beta>对羟基喹啉-甲醇包合物和对二甲氧基苯。采用偶极SASS二维核磁共振技术准确测定了甲酸钙中CH键长.用偶极SASS二维核磁共振研究了分子在包合物中的动态结构。
