MS-11: Ab initio powder structure analysis for polymorphism and phase transformation studies with pharmaceutical applications
Invited: Kenneth Harris (UK), Jim Kaduk (USA) | ||
| Session Abstract | ||
|
Chemico-physical properties of solid organic compounds considerably depend on their crystal structures. The microsymposium offers a platform of discussion on the improvement of existing methodologies of ab-initio structure solutions applied to organic compounds and the development of new ones. Examples of applications using powder diffraction data (X-rays, neutrons and electron powder diffraction) will be given, mainly in the field of pharmaceuticals, but also other organic compounds such as agrochemicals, organic pigments and proteins. Related topics such as detection and quantification of polymorphic forms with powder diffraction data are also covered. For all abstracts of the session as prepared for Acta Crystallographica see PDF in Introduction, or individual abstracts below. | ||
