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.
