Fiber diffraction
Fiber diffraction is a subarea of scattering, an area in which molecular structure is determined from scattering data (usually of X-rays, electrons or neutrons). In fiber diffraction the scattering pattern does not change, as the sample is rotated about a unique axis (the fiber axis). Such uniaxial symmetry is … See more Fibrous materials such as wool or cotton easily form aligned bundles, and were among the first biological macromolecules studied by X-ray diffraction, notably by William Astbury in the early 1930s. Fiber diffraction data led … See more The animation shows the geometry of fiber diffraction. It is based on the notions proposed by Polanyi. Reference direction is the primary beam (label: X-ray). If the fiber is tilted away … See more • WCEN — Software (Linux, Mac, Windows) for the analysis of fiber patterns • Fiber Diffraction — an introduction provided by Prof. K.C. Holmes, Max Planck Institute for Medical Research, Heidelberg. See more The figure on the left shows a typical fiber pattern of polypropylene before mapping it into reciprocal space. The mirror axis in the pattern is rotated by the angle $${\displaystyle ~\phi }$$ with respect to the vertical direction.
