Aqueous FeIVO: Spectroscopic Identification and Oxo‐Group Exchange

In Figure 1, the Mössbauer spectrum measured at 8.0 T was inadvertently also shown as that measured at 4.0 T. The revised Figure 1 shown herein contains the correct spectrum obtained at 4.0 T. The authors apologize for this oversight and would like to emphasize that the error has no bearing on any parameter reported in the manuscript and does not affect the discussion of the results. In addition, the authors would like to acknowledge the Stanford Synchrotron Radiation Laboratory (SSRL), a national user facility operated by Stanford University on behalf of the US Department of Energy, for the X-ray absorption measurements. The SSRL Structural Molecular Biology Program is supported by the Department of Energy, Office of Biological Environmental Research, and by the NIH, National Center for Research Resources, Biomedical Technology Program.1
