✦ Synopsis

The present communication reports the experimental values of NMR spin-lattice relaxation time (T 1 ) and dielectric relaxation time (τ) of piperidine, pyrrole, pyridine, diethylamine, triethylamine and pyrrolidine. The values of activation energy (ΔE A ) obtained using dielectric relaxation time, have been correlated with calculated values of ΔE A obtained using Arrhenius equation of NMR relaxation time (T 1 ) for pyridine, diethylamine and pyrrole. Authors have also established a correlation between the experimental values of NMR spin-relaxation time (T 1 ) with its calculated values obtained using different equations of dielectric relaxation time (τ).

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
