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 nonûequivalent 1H atoms, explain why there is no coupling with hydrogen atoms bonded to oxygen or nitrogen, use a chemicalûshift correlation chart to obtain information about molecular structure and 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.
