Abstract

The U.V. absorption spectra of a series of benzophenone oximes are discussed. Notwithstanding relatively small differences in absorption of the isomers, incontestable conclusions as regards configurations can be drawn, even if only one of the conceivable isomers is available. The results agree with what might be expected on the assumption that the Beckmann rearrangement proceeds via an anti‐migration.

## Abstract The infrared spectra of dilute solutions of some hydroxyacetophenones, hydroxybenzophenones and hydroxyacetonaphthones have been measured. The effect of chelation on both the hydroxyl and carbonyl frequencies has been noted.
