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...

In Raman spectrum, D2O can reduce the fluorescence of lignin and has a marked peak at 2490 cm−1. Micro-Raman system The Raman imaging data set was acquired by using a micro-Raman system (LabRam Xplora, Horiba Jobin Yvon) equipped with a confocal microscope (Olympus BX51) and a ...
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...
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...
66., 67. Biosynthesis of proteins and other cellular components like lipids can be studied with D2O, as confirmed with Raman spectroscopy for bacteria68., 69. and with SRS in in vitro and in vivo murine models.70 Moreover, SRS has been used to characterize the ER membrane and prove that...
Low-frequency Raman scatteringWaterDepolarized low-frequency Raman spectra of H2O, D2O, H2 18O, and D2 18O are measured from 266 to 350 K. The reduced Raman spectra below 250 cm-1 are reproduced by a superposition of one relaxation mode and two damped harmonic oscillators. The multiple ...
