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… Webb31 maj 2024 · 7XXU, 7XXV, 7XXW, 7XXX, 7XXY, 7XXZ.
