ABSTRACTRutherford backscattering spectrometry (RBS) is used to characterize the stoichiometry of graphite intercalation compounds (GIC). Specific application is made to several stages of different donor and acceptor compounds and to commensurate and incommensurate intercalants. A deviation from the theoretical stoichiometry is measured for most of the compounds using this non-destructive method. Within experimental error, the RBS results agree with those obtained from analysis of the (00ℓ) x-ray diffractograms and weight uptake measurements on the same samples.

AbstractIntercalation compounds of graphite with Sn(CH3)3Cl have been prepared by UV irradiation, in the presence of graphite, of solutions of Sn(CH3)3Cl, Sn(CH3)4, or of Sn(CH3)4 + SnCl4 in CCl4. Mixtures of stage 1, stage 2, and stage 3 compounds have been obtained. They were characterized by X-ray diffraction, 119Sn Mossbauer spectroscopy, and by chemical analysis. Apparently an oligomeric, anionic species is intercalated together with some solvent.

ABSTRACTCarbon 1s X-ray photoemission spectra of alkali graphite intercalation compounds are shown to provide detailed information about the distribution of charge among the carbon layers and atoms. The interior layers of higher stage compounds contain little charge and remain similar to graphite. The charge in the bounding layers is strongly localized to screen the alkali intercalate ions. The c-axis charge distribution in KC12n is in reasonable accord with the electrostatic screening model of Safran and Hamann.
