David J Philp Postdoctoral Fellow National Centre for Epidemiology and Population Health The Australian National University Graphical Representations of NMR of Quadrupolar Nuclei Wednesday 19th October 14:05-14:55pm, Carslaw Building Room 373. Nuclear magnetic resonance techniques for spin 1/2 nuclei such as 1-H and 13-C are used throughout chemistry and biochemistry; they can be intuitively understood, and used with relative ease for measuring diverse chemical and physical properties of systems. NMR spectroscopists depend heavily on graphical (rather than algebraic) representations of the underlying quantum mechanics; these graphical representations make designing and interpreting NMR experiments much easier. However, NMR techniques for spin-1/2 can only be loosely applied to quadrupolar nuclei (i.e. those with spin > 1/2). In this seminar, I will describe the basic reasons for the differences between dipolar and quadrupolar nuclei, and demonstrate a graphical representation for quadrupolar nuclei. I will demonstrate how this represenation can be used to describe and design NMR experiments.
