A nuclear magnetic resonance montage

The sensitivity of dipolar distributions/splittings to molecular geometry has long been known in solid state NMR spectroscopy. However with the increasing importance of high resolution liquid NMR spectroscopy this spatial information was replaced with narrow peaks identifying unique chemical bonding environments. Current NMR methods interface the spatial information resulting from dipolar splittings with high resolution chemical shifts by quenching one or more translation degrees of freedom in a liquid sample using liquid crystalline (LC) media. These residual dipolar couplings have become important tools for structural characterization of liquid state macromolecules.; Herein is a collection of NMR experiments to characterize molecular structure and dynamics among dipolar coupled nuclei in both the LC and solid state. Novel experiments will be presented to (1) selectively average scalar couplings independent of dipolar couplings and (2) monitor dynamics of spin clusters in the LC state. In addition, characterization of solid state group 14 nanoparticulate and molecular systems will be addressed in detail.
