Spectroscopic Studies for Rhodium (III) Binding to Apo-Transferrin

Figure 3

FT-IR spectra of free ApoHST and its Rh(III) ion coordinates, at different time intervals (15, 30, and 60 min) at physiological pH and room temperature with metal concentrations (0.5 mM) and fixed ApoHST concentration (0.5 mM; 40 mg/mL) in 4000-1000 cm^-1 range.
