Molecular structure from X-ray diffraction
While there are some developments in structure solution and refinement, these represent gradual improvements rather than fundamental leaps in methodology. An exception is the assessment of crystal quality by X-ray diffraction topography using a dedicated solid-state electronic detector; this is an elegant example where the precise physical nature of the crystal has been studied and analyzed. Si...
متن کامل3 Molecular structure from X-ray diffraction
Recent developments in the determination of molecular structures from X-ray diffraction data are discussed. While the problems associated with chemical crystallography using single crystals have largely been solved, those with structure from powders and of macromolecules are still the subjects of active research. New and improved methods in structure determination in both these fields dominated...
متن کاملModern X-ray Diffraction Methods in Mineralogy and Geosciences
A century has passed since the first X-ray diffraction experiment (Friedrich et al. 1912). During this time, X-ray diffraction has become a commonly used technique for the identification and characterization of materials and the field has seen continuous development. Advances in the theory of diffraction, in the generation of X-rays, in techniques and data analysis tools changed the ways X-ray ...

where the peak shapes were described by a pseudo-Voigt function and the background was modeled with an 6-term polynomial. Additionally, the PXRD patterns obtained at room temperature and 100 K were analyzed by Le Bail refinement using the GSAS and EXPGUI software, 2,3 where the peak shapes were described by a pseudo-Voigt function (CW profile function 3) and the background was modeled with an 4...
متن کاملActive-site studies of enzymes by X-ray diffraction methods.
X-Ray diffraction is the only method currently available for the determination of the detailed three-dimensional structure of macromolecules. In this article, the principles behind the use of X-ray crystallography in the study of protein structure are presented. The results obtained in its application to several enzymes are discussed, as well as the limitations of the method.
