NMR classes : we recommend Françoise Sauriol's online class which displays animations describing common NMR experiments using the vector model. For those who want to go further, you will find here information about the formalism of spin operators.
Joseph Hornack's online class is also very instructive and complete. If you prefer videos to readings, here is a very good class of James Keeler.
Finally, some information about the CCRMN staff is available on Slideshare.
