Introduction to NMR

The index of these notes is the place to start from. Topics with the wiki question mark lead to empty pages. The scheme will emerge first in the index, and later, sparsely, in the completed pages.

Topics that I had to lecture about, or that I had to work upon, end up here as personal notes, eventually acquiring a didactic format.

A nice, very simple introduction to NMR on the web is provided by Joseph Hornach's htbook.

1. Un peu d'histoire ...
   • The Nobel prize discoveries
2. Practical aspects
   • The Free Induction Decay and the nuclear relaxation
   • Nuclear Curie law and receptivity
3. The top and the spin
   • Classical spin precession
   • Classical spin precession in the rotating frame
   • Addition of a rotating radiofrequency field
   • Spin precession from a quantum viewpoint
   • Spin precession with the density matrix
   • A note on rotations
   • Quantum treatment of the rotating frame
   • Quantum rotating frame in matlab
   • One pulse and the Free Induction Decay

4. Static dipoles
   • Like Dense Spins
   • Unlike Diluted Spins
5. Quadrupolar interaction
6. Relaxation processes (quantum treatment)
   • T1 and T2 processes?
   • Bloch equations
   • The spin echo to measure T2?
   • The inversion recovery sequence to measure T1?
