The main application field of single-crystal X-ray crystallography is the determination of molecular structures. However, if a single-crystal diffractometer is available, the powder diffraction patterns calculated from the single-crystal data can be used to prove whether the patterns obtained with X-...
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 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...
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...
罗伦兹因子与实验方法有关,例如晶体单色器使用与否罗伦兹因子是不一样的,德拜法和衍射仪法的罗伦兹因子是不一样的。《International Tables for X-ray Crystallography》第2卷可以查到各种实验方法的罗伦兹因子。 3. 波长非单色化及色散的影响 特征辐射并不是绝对单色的X光,而是有一定的波谱分布。由于它包含一定的波长...
