Label the significant peaks in the IR and NMR spectra. When analyzing the signals in the 'HNMR, be sure to include all appropriate information. For example: 3H, singlet, 0 neighbors, and c (the letter referring to the corresponding unique type of hydrogens that were labeled in the structure). It is recommended to provide more analysis for each signal than what is described above, when necessary, such as labeling any coupling constants if any are provided For NMR label each peak...
