[en] 19F NMR spectra are presented for graphite powder reacted with SbF5, NOSbF6, NO2SbF6, graphite fibers reacted with AsF5, and polyacetylene reacted with NOSbF6 and with AsF5. For polyacetylene the linewidths imply rapid rotation and slow diffusion. For the other specimens linewidths imply that both rotation and diffusion are rapid. For SbF5 in graphite an activation enthalpy of 5+-1 kcal/mol is deduced from the observed T1 behavior. (orig.)
