rlv@physics.wm.edu Bob Vold's research is aimed at developing new techniques of nuclear magnetic resonance (NMR), and using them to study how molecular structure and motion determines the bulk properties of materials. High performance thermoplastic polymers and composites are of particular interest. For these materials, solid state 13C and 2H spectroscopy provides quantitative information about the rates and amplitudes of restricted motion of polymer segments, and how this mobility changes with polymer morphology. Novel NMR techniques, aimed at obtaining high quality spectra with very wide lines, are being explored for applications to nitrogen-containing polymers.
