Structure by single crystal X-ray diffraction

2023
Structure determination by X-ray diffraction is key to understand its function. In this chapter we have summarized the major developments in atomic structures of NCs solved by single crystal X-ray diffraction. Different techniques to grow single crystals and challenges to get good quality crystals are mentioned. We discussed various structural building

Femtosecond X-ray Diffraction on DIABN single crystals

15th International Conference on Ultrafast Phenomena, 2006
Structure sensitive methods like time-resolved X-ray diffraction and transient absorption in the mid-IR are combined with UV7VIS transient absorption spectroscopy to probe the charge transfer photo-reaction in single crystals of an aminobenzonitrile derivative.

Comparative crystal structure determination of griseofulvin: Powder X-ray diffraction versus single-crystal X-ray diffraction [PDF]

Science Bulletin, 2012
In an attempt to compare crystal structure determination from powder data and single-crystal data, crystal structure of griseofulvin (C17H17ClO6) was tested by both powder and single-crystal X-ray diffraction. Lattice parameters of griseofulvin are a=90.0°, a=b=8.9757 A, c=19.9345 A, V=1605.99 A3 from powder data coinciding with α=90.0°, a=b=8.9714 A ...

Crystal structure of the YBa2Cu3O7 superconductor by single-crystal X-ray diffraction

Nature, 1987
Just after Wu et al.1 reported superconductivity above 90 K in barium, yttrium and copper ternary oxides, the formula (YBa2Cu3O7−x) and the structural arrangement (oxygen-deficient tripled-perovskite-type structure) of the superconducting phase was proposed by different groups.

Single-crystal X-ray diffraction study of CaIrO3

American Mineralogist, 2008
Single crystals of CaIrO 3 were prepared via flux growth method. Crystal structure parameters, including the anisotropic displacement parameters, are determined based on a single-crystal X-ray diffraction experiment. The unit-cell dimensions are a = 3.147(2), b = 9.866(6), and c = 7.302(5) A.

A Low Temperature Single Crystal X-Ray Diffraction Technique

Review of Scientific Instruments, 1949
A low temperature x-ray diffraction technique, especially suitable to single crystal work, is described. Crystals are grown in glass capillaries on the x-ray camera. Position and orientation are determined with the aid of a polarizing microscope on the apparatus.

Single Crystals of Transfer RNA: An X-Ray Diffraction Study

Science, 1968
Large single crystals of formylmethionyl transfer RNA have been prepared. An x-ray diffraction study shows that the material crystallizes in a hexagonal lattice with a equal to 170 angstroms, c equal to 234 angstroms. The diffraction pattern extends to spacings just under 20 angstroms at present. The crystals are heavily hydrated, containing 88 percent
