raman-d2o光谱原理：①拉曼光谱的基本原理是基于光与分子的相互作用。当一束单色光照射到样品上时，大部分光会透过样品，只有一小部分光会发生散射。散射光中，除了与入射光频率相同的瑞利散射光外，还有频率发生变化的拉曼散射光。这是因为分子的振动和转动会引起分子极化率的变化，当光与分子相互作用时，光子与分子...
The observed Raman spectra of D2O at room temperature show not only that the liquid is stable at atmospheric pressure, but also that two other phases, deuterated ice VI and deuterated ice VII, sequentially appear above 1.2 and 2.4 GPa, respectively. The D–O stretching wavenumbers in the...
The OD stretching spectra of D2O for temperatures from 5 to 90°C and for concentrations (D2O in H2O) from 100 to 10 mol-% were studied. These spectra were treated by means of the Fourier deconvolution technique for the first time.DOI...

Raman spectra of neat glycerol, neat D2O, and glycerol/D2O solutions with glycerol mole fractions (XG) of 0.00, 0.02, 0.12 and 0.32 and 1.00 are presented. Vibrational assignments are discussed for the bands observed in the 1000–1600 and 2000–3700 cm−1 spectral regions. Upon dilution ...
Raman spectra of crystalline UO2(NO3)2·2H2O and its isotopic derivative UO2 (NO3)2. 2D2O have been investigated in the frequency range 20–3700 cm1 from 300 to 90 K. An assignment of the bands in terms of UO22+, NO3, and H2O vibrations has been proposed in the internal and extern...
Concentration Raman study of intramolecular, intermolecular and Fermi resonance interactions in the OH stretching spectra of dilute solutions of HDO in D2O using Fourier deconvolution technique The Raman OH stretching spectra of dilute solutions of H20 in D20, from 100 mole per cent to 10 mole per...
Changes in the isotropic and anisotropic component profiles of the O—D stretching bands of D 2 O were studied in the range 0–0.5 mole fraction (m.f.) of 1,4—dioxane. The contribution of the C H Raman band of dioxane was subtracted using Raman spectra of dioxane—water mixtures in ...
