Water s-retching bands of crystalline hydrates demonstrate a relative small effect of ions on water spectra. Water band shifts are mainly not bigger than in ice with some exceptions. The reasons of this observation are discussed.doi:10.1080/00387018708081554...
A molecular dynamics simulation of the Raman spectra of water in the translational and librational region is presented. Both depolarized and isotropic spectra are calculated at five temperatures in the 250-380 K range and compared with the experimental data. The relevance of 'collision-induced' ...
Spectra with relatively narrow peaks were obtained in all cases, as predicted by the first order theory of SRS. Other effects (such as multiple peaks, broadened spectra, and shifted peaks), which have been interpreted as evidence for a mixture model of water, are reconsidered, and it is ...
Selective Probing of the OH or OD Stretch Vibration in Liquid Water Using Resonant Inelastic Soft-X-Ray Scattering High-resolution O 1s resonant inelastic x-ray scattering spectra of liquid H2O, D2O, and HDO, obtained by excitation near the preedge resonance show, in th... Y Harada,T Tokush...
It has been also found that Li+ and Cs+ have siInjlar effects on the Raman spectra of water, while the effects of Na+ and K+ are very weak. 展开 关键词: Raman spectroscopy Water Hydrogen-bond DOI: 10.3866/PKU.WHXB19960208 被引量: 12 ...
The structure and H-bonding of water in an aqueous solution of the copolymer were analyzed using the contours of the O–H stretching in the polarized Raman spectra. For comparison, the H-bonded network structure of aqueous solutions of homopolymers (polyMA and polyMAPTAC) was also examined. ...
Raman spectra of amorphous solid H2O, [H2O(as)], D2O(as), and 12% H2O in D2O(as) were measured over a temperature range from 30 to 120 °K. The spectra of H2O(as) resemble those of liquid water more than they do those of ice lc or ice lh. The spectra suggest that the water ...
Low-frequency Raman spectra of ethanol−water binary solutions with varying mixing ratios are measured and presented in the form of the intrinsic Raman scattering activity, the R(ν̄) spectra. They exhibit an isosbestic point at 135 cm-1 between the pure water O−O stretching peak at 185...
RAMAN SPECTRA OF FLUID AND CRYSTAL MIXTURES IN THE SYSTEMS H2O, H2O–NaCl AND H2O–MgCl2 AT LOW TEMPERATURES: APPLICATIONS TO FLUID-INCLUSION RESEARCH A combination of Raman spectrometry and microthermometry has been applied to synthetic fluid inclusions filled with pure H2O, a NaCl brine and a ...
Both Raman and infrared spectra indicate the presence of water in the structure of dixenite. This brings into question the commonly accepted formula of dixenite as CuMn2+14Fe3+(AsO3)5(SiO4)2(AsO4)(OH)6. The formula may be better written as CuMn2+14Fe3+(AsO3)5(SiO4)2(AsO4)(OH...
