1-Dimensional Imaging Using NMR

This Immersion takes instructors through the basic concepts and measurements of Pulsed Nuclear Magnetic Resonance, including effective fields in the rotating coordinates, precession, spin-flips, relaxation processes, spin-echoes and Fourier transform spectroscopy with the goal of performing and understanding NMR Imaging. The “Block Equation” will form the theoretical basis for exploring Pulsed NMR. Pulsed NMR remains one of the most important experimental tools for physicists because it provides a unique non-invasive probe to study both the internal structure and motions of solids and liquids with magnetic nuclei. Instruments capable of these measurements are now affordable on an advanced laboratory budget.

The Session will begin by tuning the spectrometer to perform single pulse experiments in both liquids and soft solids. Then it will progress to measure both the spin-spin (T2) and spin-lattice (T1) relaxation times in these materials. We will retune the spectrometer to observe the single pulse experiments in fluorine liquids using FDFT spectroscopy. Finally, the instructors will study 1–dimensional imaging in layered soft solid samples using FFT spectroscopy.
