Raman and IR study on the H2O - CH3OH mixed solvent at 25°C using fourier deconvolution technique
Journal of Molecular Structure(1993)
摘要
The intermolecular interactions in water-methanol mixed solvent have been investigated by Raman and infrared studies of the C-H and C-O stretching bands. The Fourier deconvolution method in combination with curve fitting is used to resolve the structure of the overtone of the C-H deformation vibration 2δs in the Raman spectrum and the C-O band in the infrared spectrum. The changes in the intensities of the Fermi resonance doublet in the C-H stretching region of the Raman spectra and in the structure of the C-O infrared band are explained in terms of the hydrogen bonding interactions between methanol/methanol and methanol/water molecules.
