Figure 6
Temperature dependence of the N—D and D···O bond lengths in D-Ala (C₃D₇NO₂) are shown in panels (a) and (b). Temperature dependence of the N—D and D···O bond lengths in L-Ala reproduced from De Souza et al. (2007

) and recalculated from the data used in De Souza et al. (2009

), respectively, are shown in panels (c) and (d). The molecule is represented in the bottom left corner of the figure and labelled in agreement with Destro et al. (1988
