Abstract
We show that two widely used 2D solid-state NMR (ssNMR) pulse sequences can be implemented in an ultrafast (UF) manner, and yield 2D spectra of elastomers in a single scan, under magic-angle spinning. UF 2D ssNMR provides an acceleration of one to several orders of magnitude for classic experiments.
摘要
我们表明，两种广泛使用的二维固态核磁共振（ssNMR）脉冲序列可以以超快（UF）方式实现，并在魔角旋转下单次扫描即可产生弹性体的二维光谱。超快二维固态核磁共振为经典实验提供了一到几个数量级的加速。
