Effectiveness of high magnetic fields in high-resolution solid-state NMR: I. Case of organic compounds

Owing to recent developments of fast sample spinning and high-power decoupling, as well as application of ramp CP, advantages of high magnetic fields, namely, high sensitivity and resolution, can be fully enjoyed. 

Fig.1 and Fig.2 respectively show sensitivity and resolution enhancement in higher magnetic fields.
