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.

X-Ray Crystallography

1988
Single-crystal X-ray diffraction provides a powerful technique for precisely determining the positions of atoms in a crystal (Refs. 1, 2, which are excellent texts on crystallography). Since the first crystal structure was worked out in 1913 by W. H. Bragg, tens of thousands of crystals have been analyzed using this experimental technique.
