Learning Objectives fulfill all of the detailed objectives listed under each individual section. solve road-map problems which may require the interpretation of 1 H 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, 1 H NMR and 13 C 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. Chapter Videos This video provides an example of how to predict NMR spectra. This video provides an example of how to solve a structure determination problem. This video provides another example of how to solve a structure determination problem. 6.1: Nuclear Magnetic Resonance Spectroscopy 6.2: The Nature of NMR Absorptions 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. 6.4: Chemical Shifts in ¹H NMR Spectroscopy 6.5: Integration of ¹H NMR Absorptions- Proton Counting 6.6: Spin-Spin Splitting in ¹H NMR Spectra 6.7: ¹H NMR Spectroscopy and Proton Equivalence 6.8: More Complex Spin-Spin Splitting Patterns 6.9: Uses of ¹H NMR Spectroscopy 6.10: ¹³C NMR Spectroscopy - Signal Averaging and FT-NMR 6.11: Characteristics of ¹³C NMR Spectroscopy 6.12: DEPT ¹³C NMR Spectroscopy 6.13: Uses of ¹³C NMR Spectroscopy 6.S: Structure Determination - Nuclear Magnetic Resonance Spectroscopy (Summary)
