Abstract
By means of ESCA, IR, and NMR-F 19 spectroscopy in graphite intercalation compounds (GIC) containing ClF 3(1), ClF 5(2), BrF 3(3), and BrF 5(4) two types of CF bonds are identified. More intensive components in spectra are characteristic for (CF) bonds of GIC with halogen fluorides and the less intensive ones represent (CF) x groops. The corresponding parameters of above mentioned spectra for (CF) bonds are: C 1s - 288.5 eV, F 1s - 689.4 eV; IR peak position - 1130 cm −1, NMR chemical shift - 564 ppm. A possible origin of two additional ESCA peaks of C 1s positioned at 286.8 eV (intensive) and 291.6 (weak) is discussed breifly. An analysis of the EXAFS data for (3) and (4) compounds shows that corresponding interatomic distances BrBr, BrF and BrC are close to that known in literature for Br 2, BrF 3 and organic compounds (CBr 4). An analysis of the amplitudes and of the peak positions of the Fourier transformed EXAFS spectra made it possible to evaluate the spatial distribution of BrF 3 molecules in GIC crystal lattice. Dimers (BrF 3) 2 and polymers (BrF 3) n may be revealed by such an analysis.
