Two Modifications of Liquid Carbon Disulphide


THE data of H. Isnardi1 show that the dielectric constant of carbon disulphide undergoes at the temperature of −90° C. a sudden change. This phenomenon appears at a considerably higher temperature than the freezing point of carbon disulphide (−112°); it is thus similar to ethyl ether. On the basis of our work on ethyl ether we may therefore suppose that the carbon disulphide undergoes at −90° C. a transformation from one liquid modification into another one.
