Simultaneous Supralinear Line-Narrowing and Sensitivity Enhancement at High Fields in Magic Angle Spinning NMR of Spin-1/2 Nuclei in Solids

摘要

Advantages of very high fields in nuclear magnetic resonance (NMR) include the improved sensitivity,increased chemical shift dispersion,reduced second-order quadrupolar interactions,improved relaxation properties,and many others.Such advantages have been well demonstrated for liquids and for aligned samples.
