The spectra from 15 to 35 microns of 45 ketones, 30 ethers and 12 alcohols were analyzed and correlated. For identification purposes the data in this spectral region were shown to be useful as a supplement to data obtained in the 2-15 micron region. The spectra of ketones in the 15-35 micron region are very informative of their detailed structural features, and distinguish between aliphatic methyl ketones with and without alpha branching, aromatic methyl ketones and cyclic ketones. Tentatively, the ring size of cyclic ketones may also be determined. Study of these spectra indicates that the previous assignment of acetone is in error and a new assignment is proposed. The spectra of ethers and alcohols in the 15-35 micron region are less informative. Aliphatic ethers possess one fair group frequency, at 1/480-1/520 cm. The broad absorption by alcohols 1/650 cm was confirmed. (Author).

Progress is reported in the determination of molecular structures, characterization of materials, and the development and application of various analytical techniques. This report summarizes the three research programs undertaken and the service functions performed. The three research projects, reported in detail in separate ASD reports, concern far infrared spectra-structure correlations of ketones, ethers, alcohols and aldehydes; spark source mass spectrometry of organic compounds; and application of thermogravimetric and differential thermal analysis techniques to the characterization of high temperature polymeric systems.
