title: Comment on "Sensitive marker bands for the detection of spin states of heme in surface-enhanced resonance Raman scattering spectra of metmyoglobin" by Y. Kitahama, M. Egashira, T. Suzuki, I. Tanabe and Y. Ozaki.
abstract: We contrast recently reported surface-enhanced resonance Raman spectra (SERRS) of myoglobin on silver nanoparticles with established knowledge about this complex. We conclude that the detected bands are not related to the spin states of the protein cofactor, being rather originated by a heme coordination change induced by the metal surface.
