Experimental Studies of the Dynamic Structure of Liquids

Jiri Jonas得到理论和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。 NMR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。 本论文的主要研究内容包括五个方面：1）纳米多孔硅玻璃中液体动力学的NMR和拉曼研究; 2）氢键液体及其二元混合物的高压NMR弛豫和化学位移实验; 3）邻苯二甲酸酯模型液体分子内拉曼非符合效应的高压变温研究，考察压力和温度对构象的影响; 4）苯甲酸烷基酯的高压2D NOSEY NMR研究; 5）复杂粘性液体在1 bar至9 kbar压力范围内的动态结构的系统NMR弛豫研究。受限几何形状的液体的研究在许多领域中具有技术应用，包括催化、色谱、膜分离和地质地层中的液体渗透性，这对于三次采油是重要的。

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.
