(b) (0) Why can a single crystal be considered as a 3-D diffraction grating? (II) Explain why it is vital that monochromatic X-rays are used in single crystal diffraction studies. (2, 1 marks) (c)( Using diagrams, explain which rotation crystallographic symmetry. axes are allowed in (I) Explain what is meant by a translation in crystallographic symmetry. (IH) An atom is at an arbitrary position (u, v, w). Applying a 2-fold screw axis, explain how this atom will be translated through space. Give full details of the coordinates the atom will have in each position upon application of the screw axis, and show this in a fully labelled diagram. а (3, 1,6 marks)
