Description	18O-isotope labelled titania (anatase, rutile) was synthesized. The products were characterized by Raman spectra together with their quantum chemical modelling. The interaction with carbon dioxide was investigated using high-resolution FTIR spectroscopy, in dark and upon UV-excitation. The oxygen isotope exchange at the Ti18O2/C16O2 interface was elucidated. The C18O2 was formed as the dominating final product with a minor content of C16O18O. The rate of oxygen-isotope exchange is highly sensitive to the conditions of the titania pretreatment. The vacuum-annealed Ti18O2 at 450 C exhibited a very high spontaneous oxygen exchange activity with gaseous C16O2. A mechanism for the 18O/16O exchange process is discussed at the molecular level. The photocatalytic formation of methane, acetylene and C16O released from the Ti18O2 surface was triggered by an XeCl excimer laser irradiation. 18O-isotope labelled titania (anatase, rutile) was synthesized.
