Aims: To describe and give examples of some modern techniques for investigating the structure of a range of inorganic molecules.
Learning Outcomes: After studying the Unit, students should be able to: * Describe the physical basis, limitations and information available from a range of structural methods such as X-Ray crystallography, NMR, NQR and Mossbaurer Spectroscopies. * Solve a range of problems by critically assessing numerical and spectroscopic information * Solve problems using the techniques introduced including the application of techniques to unseen situations. Skills: Problem solving (T, F, A); Scientific writing (F, A); Independent working (F); Group working (F). Content: Brief introduction to crystallography. Crystal systems and lattices. Unit cells. Periodicity in lattices. Space group diagrams. Data collection procedures and solving crystal structures. Atomic scattering factors and structure factors. R factors. Revision of basic principles of NMR spectroscopy. Chemical shift, scalar coupling and structural elucidation using NMR. Variable temperature and 2-D NMR. NMR of paramagnetic compounds. Quadrupolar nuclei, relaxation and linewidths. |
