| Abstract: | Phase transitions have been measured by the thermodielectric effect, i.e. by the production of thermoelectrets in liquid crystals when cooling the samples from the isotropic state to the solid state. By recording the current across the samples as a function of temperature it is possible to specify very exactly the temperature at which the isotropic-liquid crystal phase transition begins. |
