Question

Draw a splitting diagram for the H_b proton if J_bc=10 and J_ba=5.

Short answer

In a splitting diagram, the NMR peaks are depicted as vertical lines, and the effect of each of the splittings is represented one at a time.

Split diagram for a given compound

• In the splitting diagram, five signals will be seen.
• The splitting diagram for b protons in the given compound is first to split into a doublet by c proton. Then these doublets are further split into triplets with the overlapping of one peak from both triplets. The intensities of overlapping peaks will be added on.
