Femtosecond x-ray crystallography

Reviews of Modern Physics, 2001
This article gives an overview of recent x-ray diffraction experiments with time resolutions down to 10^-13s. The scientific motivation behind the development is outlined, using examples from solid state physics and biology. The ultrafast resolution may be provided either by fast detectors or short x-ray pulses, and the limitations of both techniques ...

X-Ray Crystallography

2011
X-ray crystallography has been particularly important in the study of the enzyme nitrogenase, providing researchers with high-resolution structural models that have been essential to studying the enzyme's unique metal clusters and nucleotide-binding modes and protein interactions.

The Phase Problem of X-Ray Crystallography [PDF]

open access: possiblePhysics Today, 1983
With the invention some 200 years ago of the goniometer, an instrument for measuring the angles between the faces of a crystal, the science of crystallography was born. The goniometer made possible the discovery of the fundamental laws of descriptive crystallography: that the angles between the facial planes are determined by the chemical composition ...

History of X-Ray Crystallography

Chemometrics and Intelligent Laboratory Systems, 1990
A brief account is given of the history of X-ray crystallography from its beginning in 1912 to the present time. Particular emphasis is placed on the phase problem, the major obstacle in the path leading from the observed X-ray diffraction pattern to the desired crystal structure.
