Abstract: Overtone absorption lines of (CO2)-C-12-O-16 have been examined by using a tunable diode laser (TDL) spectrometer in the region around 12770 cm(-1). The spectrometer sources are commercially available double heterostructure InGaAlAs TDLs operating in the \”free-running\” mode, which allowed the detection of the line positions within 0.01 cm(-1). The observed carbon dioxide absorption lines belong to the v(1) + 5v(3) ro-vibrational band with rotational quantum number J up to 48. The minimum absorbance detected by the spectrometer (similar or equal to 5 x 10(-6)) permitted to observe the weakest lines having the absorption cross section of the order of similar or equal to 1 x 10(-27) cm(2)/molecule.
