Abstract: The experimental values of NMR spin-lattice relaxation time (T₁) of N-butylamine, di-isopropylamine, N, N, N- tributylamine, N, N- dimethylformamide, N, N- dimethylacetamide have been reported. The experimental values of T₁ have been correlated with the calculated values of T₁ obtained using various equations of the dielectric relaxation time (). It has been concluded that Murty’s equation is a better representations of the dielectric relaxation phenomenon. The values of activation energy (ΔEA) obtained using dielectric relaxation time have been correlated with calculated values obtained using Arrhenius equation of NMR spin-lattice relaxation time (T₁) for these compounds.
