After you have completed Chapter 13, you should be able to
- fulfill all of the detailed objectives listed under each individual section.
- solve road-map problems which may require the interpretation of 1H NMR spectra in addition to other spectral data.
- define, and use in context, the key terms introduced.
In Chapter 12, you learned how an organic chemist could use two spectroscopic techniques, mass spectroscopy and infrared spectroscopy, to assist in determining the structure of an unknown compound. This chapter introduces a third technique, nuclear magnetic resonance (NMR). The two most common forms of NMR spectroscopy, 1H NMR and 13C NMR, will be discussed, the former in much more detail than the latter. Nuclear magnetic resonance spectroscopy is a very powerful tool, particularly when used in combination with other spectroscopic techniques.
