Experiments using nutation interferograms and nutation spectra in nuclear quadrupole resonance (NQR) are used for the first time to find the distribution of short spin-spin relaxation times in powder samples. Instead of the traditional method of the inversion of the Laplace transform, the inversion of the integral transformations of nutation interferograms and nutation spectra are used in this work. The use of the distributions of NQR relaxation times can provide new information on dynamic processes in complex molecular systems in the solid state. To illustrate the capabilities of the method, experimental results for ³⁵Cl, ⁷⁵As NQR and for ¹H NMR are provided.

使用NQR章动实验测量短自旋-自旋弛豫时间分布。

首次使用核磁共振干涉图和核磁共振光谱在核四极共振（NQR）中进行的实验来发现粉末样品中短自旋-自旋弛豫时间的分布。代替传统的拉普拉斯变换的方法，本文使用的是章动干涉图和章动谱的积分变换的反演。使用NQR弛豫时间分布可以提供有关固态复杂分子系统中动态过程的新信息。为了说明该方法的功能，提供了³⁵ Cl，⁷⁵ As NQR和¹ H NMR的实验结果。
