A series of norborn-7-yl fluorides were synthesized and their 19F and "C NMR spectra were recorded. The 19F chemical shift trends and the one-bond carbon-fluorine coupling constants (I&) were examined and are discussed in the light of computed geometries for 7-norbornyl fluoride (4), 7-anti-norborne
## Abstract The chain dynamics of a perfluorinated ionomer, Nafionยฎ, have been studied by ^19^F and ^19^Fโ^13^C solidโstate NMR at 295 K. The backbone of Nafion is essentially poly(tetrafluoroethylene) (PTFE), which was investigated for reference. Fast uniaxial rotations of the helical backbone wer
