TR-XAS of the Fe K-edge of the Fe(II)(phen)3: laser-on (red) and laser-off (black) along with XAS of Fe(II)(2-CH3-phen)3 (blue). TR-XAS was measured in fluorescence mode. The laser excitation wavelength is 400 nm with a repetition rate of 10 kHz. Inset: molecular structure of Fe(II)(phen)3; the iron atom is coordinated to six nitrogen atoms in octahedral configuration, and each phenanthroline ligand provides two nitrogen atoms for coordination. Molecular structure drawn by VMD (Humphrey et al., 1996). |
