Abstract: Dielectric properties of argemone-mexicana oil have been investigated at various temperatures in pure form and in dilute solution of benzene at 100 kHz, 8.93 GHz and optical frequency of sodium light. The relaxation times and thermodynamical parameters have been determined from the measured data. These parameters are interpreted in terms of molecular and the intramolecular rotations. The present study suggests the existence of both the intra-molecular and overall orientations in the triglyceride molecule of argemone-mexicana oil under investigation. Study of enthalpy of activation (ΔHεHη) for dielectric relaxation and viscous flow suggests the existence of solid rotator phase in these molecules.
