Abstract

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.
