4.2 K Mössbauer spectra of anaerobically isolated IscR that has been exposed to air recorded in zero field (A) and for B = 8.0 T (B). Solid lines are simulations assuming a cluster with S = 0 using the nested set of parameters: ΔEQ(1) = -0.48 mm/s, δ(1) = 0.27 mm/s, η(1) = 0.5; ΔEQ(2) = +0.72 mm/s, δ(2) = 0.30 mm/s, η(2) = 0.5.
