Interpretation of Proton NMR Spectra

In the introductory course, you learned to use four basic kinds of information from NMR spectra number of signals, chemical-shift values, integrated signal area, and splitting patterns. We will now delve furtha- into some of these, particularly the splitting patterns. A brief correlation chart is provided in Table 10.7. More extensive listings can be found in the references.
