The position of atom m can be specified by a short vector dm that points to a location in the unit cell: 2 atoms e i m m m Ff g d g 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 r… gpu switcher tool
