We measured Raman spectra for liquid methanol, ethanol, water and their mixture under ambient conditions. We also measured these spectra for wavenumbers in the range 1400–1600 cm −1 for methanol–ethanol (4:1) and methanol–ethanol–water (16:3:1) mixtures as functions of pressure up to 62 kbar at room temperature. We present results for the wavenumber, linewidth and relative intensity of the prominent bands as functions of pressure. These results should be useful for understanding the pressure (hydrostatic) dependence of the Raman spectra of solids. Copyright © 2004 John Wiley & Sons, Ltd.
