Abstract

Synchrotron radiation (SR) can be used to collect macromolecule and small molecule crystal data whereby a variety of technically demanding problems can be solved. It is possible to measure data from small sample volumes and very large unit cells and to perform studies at the ultimate resolution of a given sample with focused, monochromatised SR. The variation of the monochromatic wavelength allows new approaches to the phase problem of x-ray crystallography. A return to the Laue method using the full polychromatic beam has allowed usable data from protein crystals to be obtained in times between seconds and nanoseconds and so offers the prospect of kinetic crystallography. Small molecule structures have now been solved with wavelength-normalised Laue data.
