Abstract
Dielectric relaxation measurements have been performed on nitropentachlorob enzene and tetrachlorometaxylene in the frequency range 100 Hz to 1 MHz and in the temperature range 152-400 K. In addition, scanning calorimetric mea surements have been carried out. From the results obtained, a possible mech anism has been suggested as regards the dielectric relaxation process.
