摘要：

In the magic angle spinning NMR experiment, a rotational resonance phenomenon occurs whenever a spin-lock rf field, ωrf, is either equal to or twice the sample spinning speed. The resonance occurs in the rotating frame where the spin-lock field assumes the role of the "Zeeman" interaction and the chemical shift modulated by the sample rotation is the "radio frequency" irradiation. The importance of good rf field homogeneity to the experiment is shown. © 1990.
