Low distance order

Low distance order is enhanced if the molecules have the shape of rodlets, which is demonstrated by the conditions giving rise to the formation of fluid crystalline phases in organic substances... 

Ordinary liquids and low molecular solutions will not yield a low angle scattering. Molecularly dispersed solutions of linear polymers may give rise to low angle scattering, which will be the more intense, the more low-distance-order (cf. p. 496) combined with associations, or swarm formation of molecular chains, occurs. Fig. 51 shows the results...
