Plotted without an x-axis, this HNMR spectrum of β-pinene demonstrates the complexity of H NMR spectra as well as the currently existing uncertainties of NMR terminology used when interpreting NMR spectra. The difficulty in formulating clear answers to the following questions exemplifies the import and breadth of this issue: Is this the entire spectrum, possibly taken at low magnetic field strength? Or is it a small segment of the spectrum? Or even a tiny portion arising from a single hydrogen, maybe acquired at ultra-high magnetic field strength? Does this plot represent a (single) resonance, (single) signal, or multiple peaks? How many peaks and how many lines does it contain? What is the meaning of the term splitting in this context? Is this an experimental or a calculated spectrum? For further inspiration regarding these questions and potential answers, see S1, Supplementary Material.
