Ferric iron protoporhyrin IX derivatives in SDS micelles have been investigated by means of visible absorption, resonance Raman, and XANES spectroscopies to establish specific correlations between the marker bands of the pentacoordinate derivatives obtained from the three different techniques. Hydroxyl and 1,2-dimethyl imidazole coordinated hemins display the typical spectroscopic marker bands of a pentacoordinate high-spin ferric iron derivative in both Raman and XANES spectra. In turn, the… CONTINUE READING
