Propose chemically sensible molecules for chemosensing. Explain the differences between Ln(III) and An(III) emission.  On successful completion of the course students should be able to:  <ul><li>Describe and explain the concepts and application of each topic (Xray diffraction, extended crystalline structures and f-block spectroscopy)</li><li>Apply the concepts of each topic and extend these to synthesise new solutions</li><li>Rationalise and interpret unseen data from each topic</li><li>Propose, and illustrate, outcomes of unseen extensions to the topic material </li></ul> <div>Concept assimilation; problem-solving skills; analytical skills; time management and organizational skills. </div> X-ray diffraction and crystallography:i. Diffraction and how crystallography takes advantage of the principle of diffraction.ii. The crystal, the unit cell and the 14 different Bravais lattices.iii.
