我们引入了一项新实验，该实验利用自旋态选择性操作在高场和超快 MAS 下对有机和生物固体进行敏感且解析的键相关。该方案是迄今为止在固体中引入的最短、最灵敏的直通键相关方法，产生均匀 C-13 标记的生物分子的分辨指纹，并构成了突出微晶样品中晶体等效分子周围轻微静态结构紊乱的工具。
We introduce a new experiment, which makes use of Spin State Selective manipulations to perform sensitive and resolved through-bond correlations in organic and biological solids at high-fields and under ultra-fast MAS. The scheme is the shortest and most sensitive through-bond correlation method introduced so far in solids, yields resolved fingerprints of uniformly C-13-labeled biomolecules, and constitutes a tool to highlight slight static structural disorder around crystallographically equivalent molecules in microcrystalline samples.
