Improper Hydrogen-Bonding CH·Y Interactions in Binary Methanol Systems As Studied by FTIR and Raman Spectroscopy

“…Methanol has been widely characterized on the basis of its infrared properties, including refractive indices, absolute integrated intensities, and dipole moment derivatives. − Similar studies have also been completed on deuterated forms of methanol: methanol- d , , methan- d 3 -ol, , and methanol- d 4 . ,, Raman spectroscopy has been shown to be a useful tool for studying the characteristics of methanol in that temperature and pressure effects on the line shapes have been examined. ,, Intermolecular interactions involving methanol have been widely studied in various organic and aqueous solvents, where the proper hydrogen bond is the main stabilizing attraction and shifts in the OH and CO stretching vibrations in both the infrared and Raman spectra have been described. Strong hydrogen bonding has been observed for the OH group in methanol in aqueous solutions − and solutions of methanol in acetonitrile, , carbon tetrachloride, ,− and hydroxy esters . Kabisch and Gruenloh compared the CO and OH wavenumbers of methanol in organic media with the respective wavenumbers of methanol in aqueous solutions .…”
