Figure 11
Directed quotient graphs of the hydrogen-bonding chains schematized in Fig. 10. Each node represents molecules and their equivalents by translation along na, . The orientations of molecules represented by white and gray nodes are related by a 2[010] rotation. Arrows represent hydrogen bonds and are labeled with the connected oxygen atoms. A voltage of 100 or on top of an arrow means that the target node is related to the corresponding node in the 0 < x < 1 unit cell by the translation along a and −a, respectively. |
