NMR relaxation studies of liquids in confined geometries

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.
