Changes in the interatomic distances of selected hydrogen bonds in DL-serine versus pressure: (a) N1—H1A⋯O3 ( ), (b) N1—H1B⋯O2 ( ), (c) N1—H1C⋯O3 ( ), (d) N1—H1B⋯O3 ( ), (e) O2—H2⋯O1 ( ); and in L-serine versus pressure: (f) N1—H3⋯O2 (-1+x, y, z), (g) N1—H3⋯O1 (-1+x, y, z), (h) N1—H2⋯O2 ( ), (i) N1—H1⋯O1 ( ), (j) O3—H5⋯O3 ( ). The figures contain data from several publications: Present contribution (black circles); Moggach et al. (2005 ) (red rhombs); Boldyreva, Kolesnik et al. (2005 ) at ambient pressure and Boldyreva, Sowa et al. (2006 ) at 4.2 GPa (blue triangles). This figure is in colour in the electronic version of this paper. |
