Description
Summary: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. [Display omitted] •Nutation were first applied in NQR to find the distribution of short T2 times in powdered samples.•Inversion of the integral transformations of nutation interferograms and nutation spectra is applied.•Experimental results for 35Cl and 75As NQR and 1H NMR are presents.
