The M4.5N4.5N4.5 Auger electron spectrum of iodine has been measured from molecular and atomic iodine vapours. The energy shift of 3.25 = 0.10 eV between molecular and atomic Auger spectra has been determined using a least-squares fitting procedure to spectra containing both molecular and atomic contributions. Different initial and final state splittings for atomic and molecular spectra, as well as the extra-atomic relaxation energy, are discussed.
