Nuclear magnetic resonance (NMR) spectroscopy. Part II

At the end of this activity, students should be able to:
– explain the coupling effect
– predict the number of components in proton NMR multiplets, given the structural formula of a compound
– draw conclusions about a molecular structure from the coupling pattern
– state and use the n + 1 rule and describe the main types of multiplet: singlet, doublet, triplet, quartet
– explain the types of coupling with non–equivalent 1H atoms
– explain why there is no coupling with hydrogen atoms bonded to oxygen or nitrogen
– use a chemical–shift correlation chart to obtain information about molecular structure
– determine the structure of organic molecules using information provided by proton NMR spectra: the number and intensity of absorption signals, the coupling pattern and chemical shifts.
