摘要：
The broadenings observed in C-13 MAS NMR spectra, which depend on the sample-spinning speed, were studied, using poly-crystalline adamantane. Not only was a monotonic increase of the linewidths with the increase of the spinning frequency observed, but also a novel resonant feature was found. The phenomena were interpreted as originating from rotary-resonance C-13-H-1 recoupling.
