Breathing : A simple and intuitive approach relates changes in bond lengths of core‐hole ionized states to the extent of vibrational fine structure, or Franck–Condon broadening (Δ E ), in X‐ray photoelectron spectra of ionic compounds. For the extreme case of a monolayer of MgO on Ag(100), the difference in Franck–Condon broadening compared to bulk MgO reflects the different binding situation in the supported oxide (see picture, r =MgO distance).
