The oldest and most precise method of X-ray crystallography is single-crystal X-ray diffraction, in which a beam of X-rays strikes a single crystal, producing scattered beams. When they land on a piece of film or other detector, these beams make a diffraction pattern of spots; the strengths and angles of these beams are recorded as the crystal is gradually rotated. Each spot is called a ref… WebNov 8, 2024 · History. Though crystal symmetry was explored in the late 1600s by Danish scientist Nicolas Steno, and continuing efforts by René Just Haüy and William Hallowes Miller in 1839 firmly established that a crystal is a ordered lattice, it wasn't until the discovery of x-rays in 1895 and the proof of their diffraction by Max von Laue in 1912 that …

WebIn a crystal, there exist directions and planes which contain a large concentration of atoms. Therefore, it is necessary to locate these direction and planes for crystal analysis and to use some conventions to specify them in a crystal. A crystallographic direction is defined as a line between two points or a vector.
