The present communication reports the experimental values of NMR spin-lattice relaxation time (T 1 ) and dielectric relaxation time (Ο) of piperidine, pyrrole, pyridine, diethylamine, triethylamine and pyrrolidine. The values of activation energy (ΞE A ) obtained using dielectric relaxation time, ha

The temperature dependence of Cs NMR and the relaxation time in a CsMnCl single crystal have been investigated 3 133 with a pulse NMR spectrometer. The Cs resonances of two different groups were obtained. The quadrupole coupling constant of Cs(I) and Cs(II) in CsMnCl decreases as the temperature inc
The behavior of 'H-nmr spin-lattice relaxation times as a function of frequency is examined for powders of a-and /3-cyclodextrins, dextran B512F, and their "deuterated" analogues, where deuterium replaces exchangeable protons. A crossover from two-to one-component relaxation decays is observed with
