WebIntroduction to Crystallography Amorphous solids are homogeneous and isotropic because there is no long range order or periodicity in their internal atomic arrangement. By contrast, the crystalline state is characterised by a regular arrange-ment of atoms over large distances. Crystals are therefore anisotropic WebThe basic principle in working of X-ray crystallography is that the crystalline atoms diffract X-rays to several specific directions whose intensity and angle of the diffracted beams generate three-dimensional (3D) electron density image from which the mean position of …
