WebAug 25, 2024 · Figure 11.8.1 The Arrangement of Molecules in the Nematic, Smectic, and Cholesteric Liquid Crystal Phases 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.
WebJan 17, 2024 · Generally, the term crystal evokes thoughts of hard and stable materials like diamond and quartz that are distinct from liquids and polymers. This hardness is mainly because the atoms are arranged regularly, forming stable structures.
