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