6. The molecular extinction coefficients of the iron complexes were deduced from the iron(III) concentration present as determined by atomic absorption. Those of the free ligand were calculated after titration of the free ligand with iron(III) (see reference 5).

8. 3 (or FeBr3) solution in 5 mM HCl. The solution was kept 18 h at room temperature, then chromatographed on an octodecylsilane column before HPLC on octadecylsilane. The pure free ligand was obtained by decomplexation of the purified complexes with EDTA as described previously.

10. The ferric halide would exist in solution as an octahedral coordination complex. However the ligands shown (Y = halogen) will only be those pertinent to the discussion of the mechanism.
