摘要: 本文从自旋-1体系自旋空间的旋转特性的讨论建议了抑制四极核旋转边带的4(π/2)脉冲系列,进而给出了一种4(π/2)-4π脉冲系列,该系列可用于获得该四极核体系的化学位移各向同性固体高分辨谱。文中给出了相应的实验结果。

Abstract: 4(π/2) pulse sequence of spinning sideband supprcsion for spin-1 nucleus is discussed, based on the rotation characteristics in the spin space of the system.4(π/2)-4π sequence, which is suitable for high resolution spectra of chemical shift in the solid state system, is also presented with experimental evidence.
