Experimental Studies of the Dynamic Structure of Liquids

Jiri Jonas获得了理论与计算化学项目的资助，继续他在液体动态结构方面的实验研究。核磁共振和激光拉曼散射技术将用于研究液体中的分子运动、分子间和分子内相互作用。研究将集中在五个方面：1)限制在纳米多孔硅玻璃中的液体动力学的核磁共振和拉曼研究；2)氢键液体及其二元混合物的高压核磁共振弛豫和化学位移实验；3)通过高压变温研究模型邻苯二甲酸酯液体分子内拉曼不符合效应，考察压力和温度对构象的影响；4)烷基苯甲酸酯的高压二维NOSEY NMR研究；5)复杂粘性液体在1 ~ 9 kbar压力范围内动态结构的系统核磁共振弛豫研究。密闭几何流体的研究在催化、色谱、膜分离、地层液体渗透率等诸多领域都有技术应用，对三次采油具有重要意义。

Jiri Jonas is funded by a grant from the Theoretical and Computational Chemistry Program to continue his experimental research in the dynamic structure of liquids. NMR and laser Raman scattering techniques will be used to study molecular motions, intermolecular and intramolecular interactions in liquids. The research will focus on five areas: 1) NMR and Raman studies of the dynamics of liquids confined to nanoporous silica glasses; 2) High pressure NMR relaxation and chemical shift experiments on hydrogen bonded liquids and their binary mixtures; 3) The high pressure, variable temperature study of intramolecular Raman non-coincidence effect in model phthalate liquids to examine the effects of pressure and temperature on conformation; 4) High pressure 2D NOSEY NMR studies of alkyl benzoates; and 5) Systematic NMR relaxation studies of the dynamic structure of complex viscous liquids over pressures ranging from 1 bar to 9 kbar.The studies of liquids in confined geometries has technological applications in many fields including catalysis, chromatography, membrane separations, and liquid permeability in geological formations which is important for tertiary oil recovery.
