Figure S1 Temperature dependence of 1H NMR spectra for bulk methanol. Asymmetric
line shape for each peak is caused by the inhomogeneity of the magnetic field, because of
the measurements without appropriate shimming. The resonance peak at 298 K has
line width of 250 Hz at the asymmetric broadening part, indicating that intrinsic line
width of the inhomogeneity of the magnetic field is less than 250 Hz. Although the
melting point of bulk methanol is 179.4 K, the drastic change in the line width was not
observed, suggesting the supercooled state of bulk methanol below 179.4 K.
Figure S2 Temperature dependence of 1H NMR spectra for bulk ethanol. Asymmetric
line shape for each peak is caused by the inhomogeneity of the magnetic field, because of
the measurements without appropriate shimming. The resonance peak at 298 K has
line width of 225 Hz at the asymmetric broadening part, indicating that intrinsic line
width of the inhomogeneity of the magnetic field is less than 225 Hz. Although the
melting point of bulk ethanol is 159 K, the drastic change in the line width was not
observed, suggesting the supercooled state of bulk methanol below 159 K.
