Non-phase shifted Fourier transform EXAFS spectra of MMOHred (A), MMOHox (B) and MMOH-RFQ (C) samples. HERFD-EXAFS (black) of M.t. MMOH is compared with the previously published PFY-EXAFS of M.t. MMOH (blue)13 and Mc (Bath) MMOH (orange). 37–38 For the FT-EXAFS from Shu, et al, a phase shift of 0.5 Å for MMOHred and 0.35 Å for MMOHox and MMOH-RFQ (see text) was subtracted from the previously published spectra to obtain a non-phase shifted FT-EXAFS for comparison. The published FT-EXAFS of Rudd et al, had no phase-shift previously applied. PFY-EXAFS of M.t. MMOH from Shu, L.; Nesheim, J. C.; Kauffmann, K.; Münck, E.; Lipscomb, J.
