Notes: The pressure dependence of the vibrational modes of propan-1- and -2-ol was measured by Raman spectroscopy up to 8 GPa at 300 K. Changes in the observed vibrational spectra indicate that the samples undergo a liquid-to-glass transition at about 4.5 GPa for propan-2-ol and about 5.5 GPa for propan-1-ol. The frequency of the O-H stretching mode (a probe of the degree of hydrogen bonding) was found to decrease at a rate of ca -28 cm-1 GPa-1 for both propan-1- and -2-ol.
