In the nematic phase, only the long axes of the molecules are parallel, and the ends are staggered at random intervals. in the smectic phase, the long axes of the molecules are parallel, and the molecules are also arranged in planes. finally, in thecholesteric phase, the molecules are arranged in layers; each layer is rotated with respect to the ones above and below it to give it this?
