NMR spectra are typically given a Figure number and a descriptive title (e.g. Figure 3. H NMR Spectrum of Liquid Unknown 11 (Diethyl ether)), and any important peaks can be labeled. On an NMR spectrum, include a structural representation of your molecule, indicating which hydrogens/carbons are represented by peaks A, B, C, etc. For example: Figure 3.
