X-ray fibre diffraction is used to study the molecular structure of long assemblies of identical subunits. Such an assembly will normally have minimum energy when all subunits have the same environment. This means that subunits in elongated assemblies follow a helix of pitch P in which subunits are related to one another by integer multiples of a unit rise p parallel to the helix axis and a unit twist p/P around this axis. Both the experimental techniques and the methods of data analysis lie somewhere between single-crystal diffraction and solution scattering, and fibre diffraction draws on both these techniques.
