Infrared Absorption Spectra of Hydrazides. I. Hydrazides of Aromatic Acids

Abstract

The infrared absorption spectra of acetylbenzoylhydrazine, trichloroacetylbenzoylhydrazine and dibenzoylhydrazine have been studied in the rock salt region. The assignment of the amide frequencies characteristic to the hydrazides RCONHNHCOR′ and the coupling between vibrations due to two CONH groups have been discussed.
