ResumoComparison of the intensities of the 19F and 1H NMR spectra of the graphite intercalation compound prepared by reaction of highly-oriented pyrolytic graphite with NO2PF6 dissolved in CH3NO2 showed that the number of CH3NO2 molecules present per PF6− ion varied from 1.64 to 1.14 depending upon sample preparation. The 1H NMR spectra of CH3NO2 in single pieces of HOPG intercalated with PF6−, AsF6−, or SbF6− show 1:2:1 triplets due to dipolar splittings resulting from partial ordering of the CH3NO2 molecules with the molecular symmetry axis parallel to the graphite planes.
