Figure 2
Effect of pressure on the crystal structure of L-serine as viewed along b: (a) L-serine-I at ambient pressure; (b) L-serine-I at 4.8 GPa; (c) L-serine-II at 5.4 GPa. This layer is referred to as the B-layer in the text. The orientations of all the diagrams are the same; the scale is the same as that used in Figs. 1 and 3. The bifurcation of the N1H5⋯O1/2 and CH⋯O bonding are shown only in the bottom-left fragment of the diagram. The colour scheme is as shown in Fig. 1. |
