Dielectric relaxation studies of argemone-mexicana oil in pure form and indilute solution of benzene at different temperatures

Dielectric properties of argemone-mexicana oil have been investigated at va rious temperatures in pure form and in dilute solution of benzene at 100 kH z, 8.93 GHz and optical frequency of sodium light. The relaxation times and thermodynamical parameters have been determined from the measured data. Th ese parameters are interpreted in terms of molecular and the intramolecular rotations. The present study suggests the existence of both the intra-mole cular and overall orientations in the triglyceride molecule of argemone-mex icana oil under investigation. Study of enthalpy of activation (DeltaH(epsi lon), DeltaH(eta)) for dielectric relaxation and viscous flow suggests the existence of solid rotator phase in these molecules.
