Heme proteins marker bands

Fig. 16 Vibrational modes of marker bands used in resonance Raman spectra of heme proteins. Vio(Aig) serves as the core size marker, i/3(Aig) and vio(Big) do as the coordination state marker, and V4 does as the oxidation state marker.

Fe(III) atom in the heme center (oxidation state marker band at 1373 cm ). At the same time, a mixture of both oxidation states in the spectra was observed and refers to a third group. Consequently, the tip was probably located right between two Cc molecules with different oxidation states. It should be noted that no direct contact of silver particle (at the TERS tip) and Cc was possible because the protein is buried in the lipid layer, whose contributions could also be identified in the spectra and actually is even domination of the spectral features.
