[en] Diode laser measurements of CO2 absorption spectra have been made in the 2,270-2,295 cm-1 spectral region at low pressure (<25 mbar) and at temperatures up to 800 K. The data are analyzed to derive squared dipole-moment matrix elements and band intensities. The results for the 01111 left-arrow 01101 band of 13C16O2 are consistent with previous measurements performed at room temperature. The values obtained for the 12C16O2 bands investigated in this work, are in good agreement with available theoretical predictions
