While in several cases, the 00ℓ domains extend across the entire width of the grain they are part of, the domains are not all the full width of the grains. Moreover, there is a clear break in the intensity between 00ℓ domains at the grain boundaries. These observations point to local, highly ordered end-to-end packing that is confined within a grain. The ordered end-to-end packing may also extend only part way across the grain, indicating a transition to nematic phases within the width of single grains.
