Abstract
The present communication reports the experimental values of NMR spin-lattice relaxation time (T1) and mutual viscosity (η12) of p-nitrotoluene, α-chlorotoluene, o-toluidine, m-toluidine and p-toluidine. The experimental values of NMR spin-lattice relaxation time (T1) and dielectric relaxation time (Ï) have been correlated with calculated values obtained using various equations of dielectric relaxation time (Ï). The correlation of dielectric relaxation time (Ï) and mutual viscosity (η12) shows that the mutual viscosity is a better representation of the resistance to the rotation of the individual solute molecule. The structural studies of these molecular species show that the process of dipole orientation is contributed by both molecular as well as intramolecular rotations.
