 Title: NMR relaxation studies of liquids in confined geometries Author(s): Xu, Shu Doctoral Committee Chair(s): Jonas, Jiri Department / Program: Chemistry Discipline: Chemistry Degree Granting Institution: University of Illinois at Urbana-Champaign Degree: Ph.D. Genre: Dissertation Subject(s): Chemistry, Physical Physics, Molecular Engineering, Materials Science Abstract: Nuclear magnetic resonance (NMR) relaxation has been used for the study of confined geometry effects on the translational and rotational dynamics of molecular liquids in sol-gel prepared porous silica glasses. The NMR relaxation times of a variety of nuclei, including $\sp1$H, $\sp2$H, $\sp{14}$N, and $\sp{13}$C, of a series of liquids with different polarities confined to the glasses, are reported as a function of pore size in the range of 12 A to 102 A. The mechanisms dominating the relaxations include dipole-dipole, quadrupole, and spin-rotation interactions. Pressure and temperature have been used as variables in the studies for enriching the experimental results.
