- Title
- Temperature dependences of the ice I hydrogen bond spectral shifts - I. The vitreous to cubic ice I phase transformation
- Abstract
- Changes in the infrared and far-infrared spectra of vitreous H$_2$O ice Iv were observed at several temperatures between 92 and 210 K during the phase transformation to cubic ice Ic. The results of the phase transformation are reported as well for D$_2$O ice I and HDO bearing ices. Between 120 $\pm$ 5 and 135 $\pm$ 5 K marked changes occurred in the structure of the spectrum as well as in the wavenumbers, half- widths and heights of the bands. Weak bands due to the stretching modes of weakly hydrogen bonded or oligomeric groups disappeared during this annealing, while modes associated with H$_2$O stretching motions shifted to lower wavenumbers by 18-42 cm$^{-1}$ and modes associated with hydrogen bond stretching and bending vibrations shifted to higher wavenumbers by 15-35 cm$^{-1}$. The results indicate that the vitreous to cubic ice I phase transformation occurred between 120 and 135 K and required less than eighteen minutes to reach equilibrium at 135 K. The bands shifted reversibly in subsequent warming/cooling cycles with $\delta_\nu_{OH}$/$\delta T$ = 0.20 cm$^{-1}$ K$^{-1}$ between 92 and 190 K.
