INFRARED SPECTRA OF ORGANOARSENIC COMPOUNDS

The infrared spectra of a wide range of organoarsenic compounds, both aromatic and aliphatic, arsenic (III) and arsenic (V), have been interpreted qualitatively. Factors considered include: (a) the dependence of absorption bands associated with phenyl ring vibrations on the presence of the arsenic atom and its substituents, and on the substitution pattern of the ring; (b) the arsenic-carbon (aliphatic) and related methylene, carbonyl and hydroxyl vibration frequencies; (c) the bands characteristic of arsonic and arsinic acids. © 1968.
