High Pressure Nuclear Magnetic Resonance Studies of Viscous Fluids
The technique of pulsed NMR is applied to the detailed study of molecular motions in a number of viscous liquids ((eta)(, )>(, )1 poise). Pressure studies are performed in order to examine explicitly the effect of volume on the motional characteristics. Where appropriate, ('13)C and ('2)D NMR are employed to obtain exclusively reorientational information, and to observe specific portions of the molecule. A prime concern of this work is to determine the validity range of the common hydrodynamic relationships at high viscosity. The overall objective of this work, then, is to provide a foundation for the systematic investigation of high viscosity fluid dynamics, as has been carried out for low viscosity liquids in this laboratory.
