For instance, O-isotope labeling would allow deeper discussion of Raman spectra, because the presence of heavier oxygen atom in the crystal lattice of titania (anatase, rutile) influences differently various Raman active vibrations of the lattice. Second motivation for synthesis of Ti(18)O(2) was the investigation of surface effects during titania/gas interaction [2]. Here we report, for the first time, the preparation of pure Ti(18)O(2) both in anatase and rutile forms. Raman spectroscopy indicated various isotope shifts for the known vibration modes of titania (anatase, rutile). The interaction with carbon dioxide was investigated with the aim to explore oxygen isotope exchange at the Ti(18)O(2)/CO(2) interface. For this purpose, high-resolution Fourier transform infrared spectroscopy of the gas phase was adopted. Workplace J.
