Infrared spectroscopic studies of supercritical fluid solutions

摘要: Near- and mid-infrared spectroscopic studies of supercritical carbon dioxide binary fluid solutions dioxide/water, argon/water, krypton/water, xenon/water as a function density are reported. The intermolecular interactions for solvent environments indicated by the IR compared to results obtained from UV-visible solvatochromic with dioxide. Infrared shifts observed in mixtures water discussed terms Onsager electrostatic theory. demonstrate that while solute induced noble gas solvents can be described simple model based upon dielectric contributions, this inadequately explains water/carbon mixtures. Further information monitoring rotational freedom directly probing spectroscopy.
