Nuclear Magnetic Resonance (NMR | INR7002U)

Description: This course will introduce students to the principles and methods of nuclear magnetic resonance. It will apply previously learned concepts to magnetic resonance. Students should appreciate the power and versatility of this technique in a variety of applications.

- Introduction: static and dynamic aspects of magnetism, Larmor precession, relaxation to equilibrium, T1 and T2, Bloch equations.

- Pulse and continuous wave methods: time and frequency domains. Manipulation and observation of magnetisation, 90 and 180 pulses, free induction decay.

- Experimental methods of pulse and CW NMR: the spectrometer, magnet. Detection of NMR using SQUIDs.

- Theory of relaxation: transverse relaxation of stationary spins, the effect of motion. Spin lattice relaxation.

- Spin echoes: "violation" of the Second Law of Thermodynamics, recovery of lost magnetisation. Application to the measurement of T2 and diffusion.

- Analytical NMR: chemical shifts, metals, NQR.

- NMR imaging: Imaging methods. Fourier reconstruction techniques. Gradient echoes. Imaging other parameters.
