4.2 K zero-field Mossbauer spectra of the reaction of the AsqJ•⁵⁷Fe(II)•2OG•2-H complex with O₂ at different times. Black vertical bars mark experimental spectra, black solid lines represent overall spectral simulations, blue solid lines represent the spectral simulation of the AsqJ•⁵⁷Fe(II)•2OG•2-H complex, red solid lines represent the spectral simulation of the oxyferryl intermediate, green solid lines represent the spectral simulations of the AsqJ•⁵⁷Fe(II)•2OG•product complex.
