Both the peaks in the spectrum are associated with one molecular
vibration, i.e. asymmetric stretching. Now, the asymmetric
stretching can occur in two different manners as shown below. That
is why we are getting two peaks.

3. (3 pts.) Shown below is the IR spectrum 2-acetylcyclohexanone (the structure is provided in the spectrum). 2- acetylcyclohexanone exists as an equilibrium mixture of diketone and two enol forms. Both the diketone and enol forms can be seen in the provide IR spectrum, although the 2 different enols cannot be distinguished. The IR spectra of both enols is essentially identical and so do not be concerned with distinguishing the enols, just assign peaks to a “generic" enol. On the...
