The Infrared Absorption Spectra of Mixtures of Acetone and Water

Abstract
A study of the infrared absorption spectra of acetone containing water revealed an associational band in the region 2.7μ. This band was studied for concentrations of water varying from 0.5 percent to 70 percent by weight. The intensity of the associational band increased with the water content of the mixture. When the water content was large, the 3μ water band overlapped the associational band. Absorption spectra were obtained for ten mixtures. It was found that concentrations of water as low as 0.1 percent could be detected by the presence of this band.
