| Abstract: | The experimental values of NMR
spin-lattice relaxation time (T1)
of m-aminophenol, p-aminophenol, o-nitrophenol, resorcinol and p-chlorophenol
have been reported. The values of activation energy (∆EA) obtained using dielectric relaxation time, have been
correlated with calculated values of ∆EA
obtained using Arrhenius equation of NMR spin-lattice relaxation time (T1) for these compounds. A
correlation between the experimental values of T1 and its calculated values obtained using different
equations of dielectric relaxation time ( ) has been established. |
