(i) The geometry of the HAN cell used to measure . A dc electric field applied along the axis produces a twist distortion. Usually and . (ii) Molecular structures and phase sequences exhibited by (a) 1,3-phenylene bis[4-(3-methylbenzoyloxy)] -dodecylbiphenyl -carboxylate (BC12) and (b) -octyloxy -cyanobiphenyl (8OCB). Temperatures are in .
