Fig. 4: X-ray absorption analyses of Th2@Ih(7)-C80.
From: Characterization of a strong covalent Th3+–Th3+ bond inside an Ih(7)-C80 fullerene cage
a L3−edge normalized μ(E) spectra of Th in Th2@Ih(7)-C80 (purple) and ThO2 (green). The inset shows an enlarged spectral range (16280–16360 eV) and the diamonds indicate the absorption edges E0. b Radial distribution function obtained by Fourier transform of k2-weighted Th L3-edge EXAFS spectrum of Th2@Ih(7)-C80 measured at room temperature. c χ(k) space (blue) and fitting curve (orange) of Th2@Ih(7)-C80. d Radial distribution function of k2-weighted Th L3-edge EXAFS spectrum and fitting curves of Th2@Ih(7)-C80, including the magnitude (R-mag in purple) and real part (R-re in blue) of the Fourier transform of the EXAFS data of Th2@Ih(7)-C80 along with their fitting curves (R-mag fitting in green and R-re fitting in orange).
