High-resolution and sensitivity through-bond correlations in ultra-fast magic angle spinning (MAS) solid-state NMR†
Abstract
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 13C-labeled biomolecules, and constitutes a tool to highlight slight static structural disorder around crystallographically equivalent molecules in microcrystalline samples.
