The plug-ins required for the interactive parts of this tutorial have become obsolete. Therefore the interactive practices are not functional any more. The readings are still available.

In response to requests from educators, Dr. Wong has decided to remake the tutorial so students and teachers who want to continue to use this tutorial can do so. Because most, if not all, students and teachers have smartphones nowadays, it makes sense that a mobile app would be a good choice for the remake.

This tutorial is now available for free as a mobile app "Simply 1H NMR Tutorial" on Google Play Store and Apple App Store.

1H NMR Intrepretation Tutorial

Proton Nuclear Magnetic Resonance (1H NMR) Spectroscopy is a powerful method used in the determination of the structure of unknown organic compounds.

During Chemistry 222 lab you will be using NMR extensively to help assign structures to two unknown organic compounds and this tutorial and exercises will hopefully help you solve your unknown.

To remind you of some things that you probably already know about the basic workings of an NMR and interpreting NMR spectra:

The 1H NMR spectrum of an organic compound provides information concerning:

  • the # of different types of hydrogens present in the molecule
  • the relative #'s of the different types of hydrogens
  • the electronic environment of the different types of hydrogens
  • the number of hydrogen "neighbor" a hydrogen has

If you feel pretty good about your knowledge of NMR, you should go directly to the exercises. If not, maybe you could visit the tutorial pages and take the included quizzes to help you remember.
