NMR spin-lattice relaxation time and activation energy in some molecular systems

The experimental values of NMR spin-lattice relaxation time (T-1) of N-butylamine, di-isopropylamine. N, N, N-tributylamine, N, N- dimethylformamide. N, N- dimethylacetamide have been reported. The experimental values of T-1 have been correlated with the calculated values of T-1 obtained using various equations of the dielectric relaxation time (tau). It has been concluded that Murty's equation is a better representations of the dielectric relaxation phenomenon. The values of activation energy (Delta E-A) obtained using dielectric relaxation time have been correlated with calculated values obtained using Arrhenius equation of NMR spin-lattice relaxation time (T-1) for these compounds.
