An in situ ESR study of Highly Oriented Pyrolytic Graphite (HOPG) indicates dramatic changes in the ESR lineshape (A/B ratio) and intensity upon exposure to fluorine or HNO3. The results can be interpreted by the formation of a macroscopic intercalat

Graphite intercalation compounds (GIC) with IF5 were investigated at 4.2 K by Mossbauer spectroscopy with the 57.6-keV gamma resonance of 127I. The identical hyperfine parameters (isomer shift, axially-symmetric electric field gradient tensor) observ

It was observed that the average creep rate during thermal cycling may show a transition period in which the average creep rate changes from a low value to a constant value. A temperature dependence of the delay time with decreasing temperature for c

Highly oriented pyrolytic graphite was fluorinated at room temperature with molecular fluorine at 2.5 atm for 8 days to 2 months without addition of any catalyst. Under these mild conditions we obtained graphite-fluorine intercalation compounds in a

We present in situ e.s.r. studies as a function of exposure time to HNO 3 . Detailed measurements at the very beginning of the intercalation process indicate a dramatic variation of the A/B ratio and intensity of the e.s.r. signal associated with the

Raman scattering spectra of stage 2 graphite fluorine intercalation compounds are presented and discussed. The concentrated sample shows four narrow lines at 1392, 1444, 1590 and 1614 cm−1. The dilute C12F spectra display two relatively broad lines

The intercalation of fluorine into HOPG is a relatively slow process and enables one to study quasiequilibrium states during the intercalation process. A very interesting ESR spectrum is observed at the initial intercalation process. The room tempera

The optical reflectivity in the visible and the near infrared of fluorine-intercalated highly oriented pyrolytic graphite compounds was studied as a function of fluorine concentration between ${\mathrm{C}}_{9}$F and ${\mathrm{C}}_{3.4}$F. Between ${\
