X-Ray sum frequency generation; direct imaging of ultrafast electron dynamics [PDF]
, 2018 X-ray diffraction from molecules in the ground state produces an image of their charge density, and time-resolved X-ray diffraction can thus monitor the motion of the nuclei.

Resonant Enhancement of Charge Density Wave Diffraction in the Rare-Earth Tritellurides [PDF]
, 2012 We performed resonant soft X-ray diffraction on known charge density wave (CDW) compounds, rare earth tri-tellurides. Near the $M_5$ (3d - 4f) absorption edge of rare earth ions, an intense diffraction peak is detected at a wavevector identical to that ...

Crystal structure of 3-bromo-2-hydroxybenzonitrile
Acta Crystallographica Section E: Crystallographic Communications, 2015 The crystal structure of the title compound, C7H4BrNO, has been determined, revealing a partial molecular packing disorder such that a 180° rotation of the molecule about the phenol C—O bond results in disorder of the bromine and nitrile groups.

A carbamazepine-indomethacin (1:1) cocrystal produced by milling [PDF]
, 2011 An X-ray amorphous mixture of carbamazepine and indomethacin transforms upon annealing to produce a novel 1:1 cocrystal, whose structure has been determined from laboratory powder X-ray diffraction (PXRD ...

The Limits of X-ray Diffraction Theory
Crystals, 2023 X-ray diffraction theory allows the interpretation of experiments to build a structural model that fits the collected data. As with any experimental science, the observations are subject to uncertainty through the instrument and user limitations ...

Subpicosecond X-ray diffraction
Laser and Particle Beams, 1994 With the advent of ultrashort (subpicosecond) high-power lasers it is now possible to create intense bursts of X-rays with subpicosecond durations. An analysis of the temporal response of diffraction of such X-rays by crystals in both the dynamical and kinematic regime is presented. It is also shown that under certain conditions the temporal resolution
