FSLG CPMAS HETCOR 是一项 2D 固态 NMR 实验,可提供 1H 和 X 核之间的结构信息和构象相关性。然而,该实验的实际应用遇到了间接1H维上的化学位移参考问题。在我们的论文中,我们提出了一种基于 1H–1H MAS FSLG 的新颖方法及其应用来引用 FSLG CPMAS HETCOR,该方法克服了 2D 1H-X HETCOR 实验中的 1H 引用。无论样品类型如何,这种方法在很宽的温度范围内都能很好地发挥作用。
FSLG CPMAS HETCOR is a 2D solid-state NMR experiment which provides structural information and conformational correlation between a 1H and an X-nucleus. However, practical application of the experiment suffers from the chemical shift referencing problem on the indirect 1H dimension. In our paper, we present a novel 1H–1H MAS FSLG-based approach and its application to reference the FSLG CPMAS HETCOR which overcomes the 1H referencing in the 2D 1H-X HETCOR experiment. This approach works excellently irrespective of the sample type over a wide range of temperature.
