Infrared spectrum of n-nonanoic acid.between 1200 and 1300 cm–^1 is considerably intensified. It should be noted that in the spectra of acids
the C—H stretching band is frequently observed as a sharp peak above the broad O—H band.
The final spectrum (Figure 9.24) is that of p-nitroaniline. Although complex it is immediately
recognizable as being aromatic (C–H above
