Figure 6

Field-dependent Mössbauer spectra of a sample containing 7 mM 57Fe(II)-ZnPPFeBMb1, and 20 eq. of NO in 50 mM Bis-Tris pH 7.3, collected at 4.2K. Black dots: experimental data; black lines: sum of fit; gray solid line: ferrous S=2 starting material; gray dashes: S=3/2 {FeNO}7 component in intermediate relaxation; gray short dots: magnetically split S=3/2 {FeNO}7 component. Only the splitting pattern of 65% S=3/2 {FeNO}7 species is shown in high field. The S=3/2 species at all fields was simulated using a slow relaxation model. The S=2 species in low-field was simulated as Lorentzian. (See Figure S15 for a color representation of this figure).
