Infrared spectra have been recorded of the following mono-, di-, and tri-ethylene glycol monoalkyl ethers: C n H2 n+ 1OCH2CH2OH where n= 17 and 19; C n H2 n+ 1 (OCH2CH2) 2OH where n= 17, 18, 19, and 22; and C18H37 (OCH2CH2) 3OH. Spectra of the pure liquids, solutions in CCl4, and the solids at room and liquid air temperatures have been studied. From a study of the CH2 rocking modes at 927-934, 889, 900, and 862 cm-1 ...
