Sr–fresnoite determined from synchrotron X-ray powder diffraction data
The fresnoite-type compound Sr2TiO(Si2O7), distrontium oxidotitanium disilicate, has been prepared by high-temperature solid-state synthesis. The results of a Rietveld refinement study, based on high-resolution synchrotron X-ray powder diffraction data, show that the title compound crystallizes in the space group P4bm and adopts the structure of other fresnoite-type mineral samples with general...
متن کاملClarithromycin form I determined by synchrotron X-ray powder diffraction.
The structure of the metastable form I polymorph of the macrolide antibiotic clarithromycin, C(38)H(69)NO(13), was determined by a powder diffraction method using synchrotron radiation. The space group of form I is P2(1)2(1)2. The initial model was determined by a molecular replacement method using the structure of clarithromycin form 0 as a search model, and the final structure was obtained th...
متن کاملDynamic Powder Crystallography with Synchrotron X-ray Sources*
The increased brightness, tunability, low divergence and low emittance of X-ray beams available at synchrotron X-ray sources facilitate a variety of powder-diffraction experiments not practical using conventional in-house sources. Furthermore, the increased availability of fast position-sensitive detectors, along with implementation of improved software, make possible new classes of experiments...
متن کاملLaser and synchrotron radiation pump–probe x-ray diffraction experiments
Recent developments have allowed x-ray diffraction techniques at synchrotron radiation facilities to be employed with a temporal resolution of around 1 ps. These developments are the availability of firstly, high brightness third-generation x-ray sources, secondly, passively mode-locked lasers with 100 fs temporal duration and thirdly, averaging streak cameras with sub-picosecond temporal resol...
متن کاملContemporary X-ray electron-density studies using synchrotron radiation
Synchrotron radiation has many compelling advantages over conventional radiation sources in the measurement of accurate Bragg diffraction data. The variable photon energy and much higher flux may help to minimize critical systematic effects such as absorption, extinction and anomalous scattering. Based on a survey of selected published results from the last decade, the benefits of using synchro...
