Abstract: 532nm pulsed laser-ablated Ta atoms react with carbon dioxide to form products TaCO, OTaCO and O2Ta(CO)2, which have been isolated in argon matrices and identified by their FTIR spectra and a comparison of the spectra of OxW(CO)y. Annealing of matrix isolated sample results in the growth of OTaCO and O2Ta(CO)2, and further 266nm laser irradiation leads to the increase of OTaCO as well as the formation of O2TaCO.

Key words: Matrix isolation, FTIR spectra, Laser ablation, Ta, Carbon dioxide
