摘要：

Variable‐angle sample‐spinning (VASS) NMR was investigated for the case of limited rotation speed of the spinner. Side‐band intensities and line‐shapes for the central transition of half‐integer quadrupolar spin nuclei were calculated as a function of the parameter \documentclass{article}\pagestyle{empty}\begin{document}$ X = \frac{1}{4}[I(I + 1) - \frac{3}{4}]v_{\rm Q} ^2 (1 + \eta ^2 /3)/v_{\rm L} v_{\rm R}$\end{document}. It is shown that complex sideband patterns can be analysed using a very fast computational program. Copyright © 1990 John Wiley & Sons, Ltd.
