Structural elucidation is essential in all areas of chemistry, from understanding the behaviour of engineered enzymes or functional materials, to the creation of new medicines to treat disease. This course describes the fundamentals of chemical structure and symmetry, and the use of molecular orbital theory and quantum mechanics to understand molecular properties and chemical spectroscopy. It has a major focus on problem solving and acquiring applied skills to deploy concepts of symmetry, spectroscopy, spectrometry and diffraction to define chemical structure across all states of matter. Advanced research-level strategies for elucidating complex structures will be developed by connecting the partial structural information obtained from infra-red spectroscopy (IR), UV-visible spectroscopy, 1D and 2D nuclear magnetic resonance (NMR) spectroscopy, mass spectrometry (MS) and X-ray crystallography.
This course is co-taught with undergraduate students but assessed separately
Learning Outcomes
Upon successful completion, students will have the knowledge and skills to:
- Critically analyse symmetry operations and their use in determining the point group of a molecule and the space group of a crystal.
- Construct advanced qualitative molecular orbital diagrams for diatomic, triatomic and polyatomic molecules through expert consideration of molecular symmetry.
- Critically analyse, interpret and predict vibrational and electronic spectra of molecules through consideration of molecular orbitals and symmetry.
- Expertly determine crystal structures from single crystal X-ray diffraction data, including the critical analysis of discrete and extended structural features.
- Critically evaluate the roles and limitations of various forms of spectroscopy, spectrometry and diffraction.
- Develop complex problem solving strategies and critically apply data derived from infra-red spectroscopy (IR), UV-visible spectroscopy, 1D and 2D nuclear magnetic resonance (NMR) spectroscopy, mass spectrometry (MS) and diffraction to deduce the structure of chemical compounds.

The ANU uses Turnitin to enhance student citation and referencing techniques, and to assess assignment submissions as a component of the University's approach to managing Academic Integrity. While the use of Turnitin is not mandatory, the ANU highly recommends Turnitin is used by both teaching staff and students. For additional information regarding Turnitin please visit the ANU Online website.
Workload
The expected workload will consist of approximately 130 hours throughout the session including:
- Summer session: 10 x 3 hour lectures plus 10 x 3 hour workshops over the intensive 2 week component.
- Sem 1: Face-to face component which may consist of 3 x 1 hour lectures plus 1 x 3 hour workshops per week
- Plus approximately 65 hours of self-study which will include preparation for lectures, workshops and other assessment tasks.
