N2 - To gain more understanding into the mechanism that enables the dramatic resonant Raman enhancement of
totally symmetric modes observed in hemozoin (malaria pigment) and other related heme supramolecular
arrays when applying near-infrared excitation wavelengths, the iron(III) porphyrins Fe(TPP)Cl, [Fe(TPP)]2O,
Fe(OEP)Cl, and [Fe(OEP)]2O along with -hematin (synthetic hemozoin or malaria pigment) were analyzed
in the solid state using resonance Raman spectroscopy. The critical finding was that from the model compounds
investigated, all except [Fe(OEP)]2O exhibited the enhancement of the totally symmetric mode I?4 when exciting
the molecules with 782 and 830 nm laser lines.
