The IR spectra of Nujol is given on the following page (it acts like a baseline spectra). In the IR spectra of dibenzalacetone below, cross out (with an X) the peaks attributed to Nujol (and label them as Nujol). Then, label the characteristic peaks of dibenzalacetone.

The IR spectra below was taken in Nujol. Nujol is a mineral oil used to create a
thick suspension with a solid product. However, it also adds peaks to an IR
spectra. The IR spectra of Nujol is given on the following page (it acts like a
baseline spectra). In the IR spectra of dibenzalacetone below, cross out (with an
X) the peaks attributed to Nujol (and label them as Nujol). Then, label the
characteristic peaks of dibenzalacetone.
