The passage around this formula
Powder X-ray diffraction (XRD) is usually the first structural measurement run on a new crystalline material, because it is fast, non-destructive, and statistically representative — a powder sample presents billions of randomly oriented crystallites to the beam, and the resulting pattern of peak positions and intensities is a fingerprint of the unit cell and its symmetry. Peak positions locate the lattice through Bragg’s law, . where is the known X-ray wavelength, d is the spacing between a family of lattice planes, and is half the scattering angle at which a peak appears. Peak positions alone give the lattice parameters; peak intensities and shapes carry…
