Methods of analysis of Fe(VI) moieties documented in literature sampled between 2016–2021. (Spectral methods: IR = infrared/reflectance/Fourier Transform, XRD = X-ray diffraction, XPS = X-ray photoelectron spectroscopy, EPR = electron paramagnetic resonance, UV-Vis = ultraviolet & visible, followed by Raman spectroscopy, Magnetic Susceptibility, Mössbauer spectroscopy and XANES = X-ray absorption near-edge spectra).
