Effects of Certain Liquids on the OH Vibrational Band of Alcohol

Transmission curves for several different concentrations of methyl alcohol in dioxane, methyl cyanide, isopropyl ether, benzene and carbon tetrachloride, and of ethyl alcohol in dioxane were obtained in the region $2.55 \mu$ to $3.15 \mu$. Dioxane, methyl cyanide, and isopropyl ether were found to shift the OH vibrational alcohol band to the shorter wave-lengths and to increase its intensity appreciably. There appeared to be no definite relationship between these changes and the electric moment of the solvent molecule. It is suggested that these variations indicate some type of interaction of the solvent molecule with the OH group. It may be possible to interpret the results as indicating a linkage of the solvent molecules with those of the alcohol through the formation of hydrogen bonds.
