Diagram illustrating the simulation of the Mössbauer spectra of [Fe(TpivPP)(1-EtIm)(O2)] using the Oldfield approach. Parameters: QS= −2.09 mm/s, η= 0.12, energy difference = 123 cm−1, line width = 0.24 mm/s, rate of interconversion = 2.55 × 106 sec−1 (50 K), 6.36 × 108 sec−1 (250 K). Fit residuals between the experimental data and the simulation are shown as the top line.
