Total Scattering Study of the Defect Structure of Gamma Glycine

Abstract: Our picture of the structure of organic solids is derived almost exclusively on ?conventional? crystal structures based on Bragg scattering. Though it is hard to overstate the success of this approach, it does yield an average view of the crystalline state, and this is a substantial approximation in the context of dynamic phenomena like phase transitions. The thermodynamically most stable gamma polymorph of glycine transforms to the alpha form at around 440 K, though the exact temperature depends on sample history: annealing the sample causes the temperature of the transition to increase. In this study we will collect data suitable for total structure modelling before and after annealing the sample with the aim of characterising changes in the defect structure. The data will provide an atomistic view of the structure on the local scale as it undergoes change.
