To describe and give examples of some modern techniques for investigating the structure of a range of inorganic molecules.
After studying the Unit, students should be able to:
* Describe the physical basis, limitations and information available from structural methods, namely, X-Ray crystallography and NMR spectroscopy.
* 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.
Problem solving (T, F, A), Scientific writing (F, A), Independent working (F), Group working (F).
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.
Theoretical basis of NMR spectroscopy. Spin-spin coupling and chemical shifts in NMR spectroscopy and the factors that affect them. Spin systems.
