The application of nuclear magnetic resonance methods to the study of compl
ex fluids under shearing and extensional flows is reviewed. Both NMR veloci
metry and spectroscopy approaches are discussed while specific systems stud
ied include polymer melts, rigid rod and random coil polymers in solution,
lyotropic and thermotropic liquid crystals and liquid crystalline polymers,
and wormlike micelles. Reference is made to food systems.
