n.m.r. Studies of Supercooled Viscous Fluids and Silica Gels (Nmr)

Pulsed N.M.R. techniques are used to study the dynamic behavior of viscous fluids ((eta) > 1 Poise) in the supercooled state. The applicability of the hydrodynamic equations to high viscosity systems is investigated at a molecular level in a series of selectively deuterated compounds of varying molecular symmetry and structure. Pressure is used as an experimental variable to extend the range of observable viscosities, and in addition to separate the effects of kinetic energy and density on the molecular interactions in the supercooled state.
