在4°-27 ° K的温度范围内，观察到了悬浮在固体Ar中的H2O、HDO和D2 O的高分辨率光谱。已获得的证据，这些物种在Ar矩阵的旋转。大多数观察到的线被发现与气体光谱的低J跃迁非常一致，允许小的矩阵位移。已经观察到由H2O和D2 O的自旋修饰引起的跃迁，并且观察到的强度表明已经发生了很大程度的自旋平衡。这可能是由于O2的少量污染。讨论了ν2-H2O转动能级的微扰。
High‐resolution spectra of H2O, HDO, and D2O suspended in solid Ar have been observed in the range 4°—27°K. Evidence has been obtained for the rotation of these species in Ar matrices. The majority of the observed lines are found to be in very good agreement with low‐J transitions of the gas spectra, allowing for a small matrix shift. Transitions arising from both spin modifications of H2O and D2O have been observed and the observed intensities suggest that a large degree of spin equilibration has taken place. A small contamination of O2 may be responsible for this. A perturbation of one of the rotational levels of ν2—H2O is discussed.
