The registration of spectra (in the range 10–4000 cm−1) of spontaneous Raman scattering in protium and deuterium water, as well as in its mixtures, is reported. The mixtures were prepared with different volume ratios of light and heavy water (from 5:1 to 1:9). As a result of taking into account the Bose factor in the low-wavenumber region, bands corresponding to the cluster translational modes of water were found. A change in the Raman shift of cluster modes depending on the isotopic composition of a mixture of liquids was recorded. In the wavenumber range 1000–1700 cm−1, the manifestation of deformation modes of H2O, D2O, and HOD molecules was found in the Raman spectra. Stretching vibrations of mixtures of light and heavy water correspond to the wavenumber range of 2000–4000 cm−1. The obtained dependences of the scattered radiation intensity were used to construct difference spectra, which made it possible to determine the content of D2O molecules in light water. The presented experimental results are of interest for diagnosing the presence of deuterium water in the biosphere and for analyzing nonlinear optical processes in water.

轻水和重水混合物中的自发拉曼散射
报道了在氘和氘水及其混合物中的自发拉曼散射光谱（在 10–4000 cm -1范围内）的配准。用不同体积比的轻水和重水（从 5:1 到 1:9）制备混合物。由于考虑了低波数区域的玻色因子，发现了对应于水的簇平移模式的波段。记录了取决于液体混合物的同位素组成的簇模式的拉曼位移的变化。在1000~1700 cm -1波数范围内，H 2 O、D 2的变形模式表现在拉曼光谱中发现了 O 和 HOD 分子。轻重水混合物的拉伸振动对应于2000-4000 cm -1的波数范围。获得的散射辐射强度依赖性用于构建差分光谱，这使得确定轻水中D 2 O分子的含量成为可能。所呈现的实验结果对于诊断生物圈中氘水的存在以及分析水中的非线性光学过程具有重要意义。
