ABSTRACT

The molecular ion (m/z 224) is the base peak of the mass spectrum where two abundant peaks corresponding to the loss of aromatic units (m/z 147, M-77 or m/z 120, M-104) and the fragments themselves (m/z 104 and 77) can be easily distinguished. The aromatic ring of the compound is confirmed by the infrared spectrum, which shows the Car-Car stretching vibrations at 1605 and 1576 cm–1. Moreover, a strong absorption at 1667 cm–1 reveals the presence of a carbonyl group.
