The infrared absorption of liquid 1,4-bis(trifluoromethyl) benzene has been obtained in the region 2–22μ with the aid of LiF, NaCl, and KBr prisms. The Raman spectrum has been photographed with a three-prism glass spectrograph of linear dispersion 15A/mm at 4358A. A nearly complete assignment of fundamental vibration frequencies is given, and the spectra are interpreted in detail.

Gas chromatography is a valuable analytical tool for the measurement of volatiles in a variety of different samples. Published methods utilizing this technique for the analysis of ethanol and related volatiles in blood and urine are now too numerous to mention. However, in a recent publication by Jain, a simple, rapid gas chromatographic method for the simultaneous determination of methanol, ethanol, acetone, isopropanol, as well as low boiling hydrocarbons associated with glue sniffing was described. The method involves the direct injection of blood mixed with an internal standard. Jain reported the successful use of his G.C. column for more than two years and several thousand injections.
