EXPERIMENTAL STUDIES OF SOLUTION PROCESSES: VI. EFFECT OF SOLVENT ON INFRARED ABSORPTION SPECTRA

Abstract

Here are reported infrared absorption data between 4000 cm−1 and 700 cm−1 near 19 °C for methanol, n-propanol, isopropanol, cyclohexanol, benzyl alcohol, diethyl ether, anisole, 1,4-dioxane, diisopropyl ether, nitromethane, acetone, p-xylene, benzene, and hexane as pure substances and in carbon tetrachloride solution. Band frequencies accurate to within 1 cm−1 are reported. Except for the 3340 cm−1 band in dilute MeOH solutions no frequency shifts were observed even with gross changes of the electrical properties of the solutions. Molar extinction coefficients at absorption maxima are discussed briefly.
