X-ray crystallography n (General Physics) the study and practice of determining the structure of a crystal by passing a beam of X-rays through it and observing and analysing the diffraction pattern produced Collins English Dictionary – Complete and Unabridged, 12th Edition 2014 © HarperCollins ...
X-ray crystallography is a technique that uses X-ray diffraction patterns to determine high-resolution, three-dimensional structures of molecules such as proteins, small organic molecules, and materials. The substance of interest must be in crystalline form, which typically requires testing various crys...

所以要描述X-ray Crystallography需要有兩組座標系統,一個是用來描述光柵的行為,稱為Real Space;另一個則是描述干射出來的圖形,成之為Reciprocal Space,須把兩種座標系連接起來才可正確的作結構分析。 3、Unit Cell: Crystal可以為任何結構分子,當分子很複雜難以描述時可把每個分子當成點(Lattice Point),而分子所...

X-ray data collection is mainly performed on a monthly schedule at the industrial synchrotron beamlines (at SSRF or Spring-8), ensuring the highest resolution for the crystal structure. For each protein crystallography project, we accelerate data processing and structure solutions via automated programs...

2.6.1X-Ray crystallography AsFig. 1shows,X-ray crystallographyis arguably the most widely used biophysical technique in medicinalchemistry. In single-crystal X-Ray a monochromatic beam of X-Rays, which can be considered as electromagnetic waves, is directed at the crystal and the diffraction patte...
