Fermi resonance was observed between the OH stretch and the overtone of the OH bending modes of HDO molecules contaminated in phase VII of D(2)O ice over the pressure range from 17 to 30 gigapascals. An anharmonic coupling constant, which is related to the potential energy surface on which hydrogen-bonded protons oscillate, was found to range around 50 wave numbers through the resonant pressure range. Its experimentally obtained magnitude and pressure-insensitive behavior will be useful for theoretical studies of the potential energy surface and hence of the nature of hydrogen bonding in ice.
在压力范围为 17 至 30 千兆帕斯卡之间，观察到了 D(2)O 冰相 VII 中污染的 HDO 分子的 OH 伸缩和 OH 弯曲模式的泛音之间的费米共振。发现通过共振压力范围，与氢结合质子振动的势能表面有关的非谐耦合常数约为 50 波数。其实验获得的大小和对压力不敏感的行为将有助于对势能表面的理论研究，从而有助于对冰中氢键的性质的研究。
