Abstract:

 The experimental values of NMR spin lattice relaxation time (T1) of 2-aminopyridine, 3-Aminopyridine, 4-Aminopyridine, 2-Chloropyridine and 3-Bromopyridine have been reported. These values of T1 have been correlated with the calculated values of T1 obtained using various equations for dielectric relaxation time (t). This comparative study concludes that the values of dielectric relaxation time and NMR spin lattice relaxation time obtained using Murty equation are in better agreement with the experimental values. Experimental values of the mutual viscosity (n) of 2-aminopyridine, 3-Aminopyridine and 4-Aminopyridine have been also reported. It has been concluded that the mutual viscosity is a better substitute for the resistance to the rotation of the individual solute molecule.
