O 1s core level and valence band photoelectron spectroscopy data have been acquired from adsorbate-free TiO 2(110)(1 × 1) in ultrahigh vacuum. Careful analysis of the O 1s spectra demonstrates that there is no distinct feature arising from twofold coordinate surface bridging oxygen atoms. This result resolves apparent ongoing confusion in the literature about this issue. © 2012 American Physical Society.
