The X‐ray photoelectron spectra of metallic iridium and the technologically important iridium compounds, IrO2 and IrCl3, have been studied. The results not only improve the accuracy of published data but also expand the binding energy database of other iridium core‐levels. The difference between anhydrous and hydrated materials is explored, and the effect on curve‐fitting is discussed, together with the derivation of suitable line shapes for peak fitting of data acquired from a conventional monochromatic Al Kα X‐ray source.
