Abstract: | Vibrational frequencies vOH and vOD have been measured for isotopically-dilute HDO molecules in eleven solid hydrates at 90 K. The results have been used to prepare a plot of the ratio vOH/vOD versus vOH. The ratios fall on a smooth curve and decrease with decreasing frequencies vOH. The anharmonicity constants ωexe have been estimated. They were found to increase with decreasing vOH. |
