- 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 5, you learned how an organic chemist could use infrared spectroscopy to assist in determining the structure of an unknown compound. This chapter introduces 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.

- 6.3: The Chemical Shift
- We shall try to focus on the interpretation of NMR spectra, not the mathematical aspects of the technique. In this Section, we discuss 1H NMR chemical shifts in more detail. Although you will eventually be expected to associate the approximate region of a 1H NMR spectrum with a particular type of proton, you are expected to use a general table of 1H NMR chemical shifts.
