Figure 1

FT-IR spectra of the S-H stretching region. FT-IR spectra of Hb A (top), NEM-L Hb A (center) and NEM-H Hb A (bottom) in the 2500-2700 cm-1 S-H stretching region are shown. Sample concentration was 6-7 mM Hb, in a 0.1 M potassium phosphate buffer, pH 7.1. Curve fits were performed using a mixed Gaussian/Lorentzian peak fitting function and are shown with dotted lines. Spectra have been arbitrarily displaced vertically.
