Abstract

We present an extension of magic angle coil spinning (MACS) solid-state NMR spectroscopy to double-resonance experiments, enabling implementation of powerful double-resonance solid-state NMR methodologies including cross polarization, proton decoupling, and two-dimensional correlation spectroscopy etc., while still enjoying the merits that are intrinsic to MACS, such as high concentration sensitivity, eliminated magnetic susceptibility-induced field distortion, and an easy-to-use approach with the conventional and widespread hardware.

摘要

我们提出了一种将魔角旋转（MACS）固态 NMR 光谱学扩展到双共振实验的方法，从而能够实现强大的双共振固态 NMR 方法，包括交叉极化、质子去耦和二维相关光谱等，同时仍然享受到 MACS 固有的优点，例如高浓度灵敏度、消除了磁化率引起的磁场变形，以及使用传统和广泛的硬件的简便方法。
