The oxidation state of the central atom M in intercalation compounds of the form C n MF x can be determined by examination of the chemical shift of the fluorine magnetic resonance. For reaction of graphite with XeF 6 , XeF 4 , and IF 7 , the central

Reduction of perylene with potassium metal in tetrahydrofuran at room temperature yields the dianion, as determined by potassium metal uptake, by 1H NMR of the anion solution, and by product analysis of a methyl iodide quench. There is no evidence fo

IF 7 intercalates into graphite accompanied by the partial fluorination of the graphite host. The intercalated species was identified as IF 5 by IR and 19 F nmr spectroscopies. Mass spectrometric analyses of the gases evolved from the intercalate sho

Nuclear magnetic resonance experiments, involving both chemical shift and spin-spin coupling determinations, are used to show the presence of ions in intercalation compounds of graphite created from entirely neutral molecular reagents. Specifically,
