Abstract 19F NMR results are reported on first stage SbF5-GIC and second stage AsF5-GIC as a function of temperature. Above a “cutting temperature”, we postulate the existence of two fluorine population at least, which we have tried to identify on our spectra according to a pentafluoride oxidation reaction. The results are correlated with a charge transfer coefficient evolving with temperature, and are discussed in comparison with other experimental results.
