WebFor example, the most characteristic absorption band in the spectrum of 2-hexanone (Figure 6.3a) is that from the stretching vibration of carbonyl double bond C=O at 1716 cm-1. It is a very strong band comparing to the others on the spectrum. A strong absorbance band in the 1650–1750 cm-1 region indicates that a carbonyl group (C=O) is present. WebOn our IR spectrum, it occurred at 2902.90 cm -1 to 3090.58 cm -1, with the largest peak at 3018.05 cm -1. The carbonyl peak occurs between 1650 cm -1 to 1750 cm -1 and the alcohol peak occurs at about 3600 cm -1. Our product had the C=O bond, and therefore it did indeed show up on the IR spectrum at 1656.21 cm -1.
