The determination of molecular structure underpins all aspects of synthetic chemistry. There are many techniques available to determine the precise structure (connectivity, conformation, stereochemistry, chirality) of a molecule. X-ray crystallography is the most direct technique for molecular structure determination. Crystallography will be presented in this course in a series of lectures and problem based learning sessions. As a complement to the lecture material all students will undertake a computer based exercise as part of their assessment where they solve and refine a real crystal structure. Nuclear Magnetic Resonance (NMR) and mass spectrometry are used routinely in the characterisation of new and existing compounds. Simple 1-D and more sophisticated 2-D NMR experiments can lead to information that, if interpreted correctly, enable the assignment of connectivity and stereochemistry. The NMR section of this course will be presented as a series of lectures and problem solving sessions. An assignment using several spectroscopic techniques to assign the structure of an unknown compound will be part of the overall assessment of this section of the course. This course provides students with requisite skills and knowledge to characterise new or existing chemical compounds in a research or quality control/analytical laboratory setting.
Prior to 2018, the prerequisite knowledge for this course now in CHEM2054 was covered in CHEM2050/CHEM2901.

See 1.1ᅠCourse Details.

Course requirements

Assumed background

In addition to completion of first level Chemistry (CHEM1100 and CHEM1200), it is assumed that students have completed CHEM2054, which provides essential background to NMR spectroscopy.

Task description

Solution and refinement of the crystal structure of an unknown compound including a written report describing the structure and comparing it with similar compounds in the literature.

Use of Artificial Intelligence (AI) and Machine Translation (MT)

This task has been designed to be challenging, authentic and complex. Whilst students may use AI and/or MT technologies, successful completion of assessment in this course will require students to critically engage in specific contexts and tasks for which artificial intelligence will provide only limited support and guidance.

A failure to reference generative AI or MT use may constitute student misconduct under the Student Code of Conduct.

To pass this assessment, students will be required to demonstrate detailed comprehension of their written submission independent of AI and MT tools.

Hurdle requirements

Completion and submission of this assignment is essential for a grade higher than 3
