Quantum Description of Pulsed NMR

This lecture covers the principles of Pulsed NMR Spectroscopy, including the Zeeman interaction, chemical shift, scalar coupling, and dipolar coupling. It delves into the quantum mechanics behind nuclear magnetic moments, bulk magnetization, and the rotating frame. The presentation explores the dynamics of transverse magnetization, resonant pulses, and the manipulation of spins through radiofrequency irradiation. It discusses the density operator, the Schrodinger equation of motion, and the Liouville-von Neumann equation. The lecture concludes with insights on the effective fields in the rotating frame, resonant pulses, and the detection of NMR signals.
