Abstract: | Positions and intensities for 453 spectral lines in 12 rovibrational bands of 12C16O2 have been determined between 3700 and 3750 cm−1. At three temperatures (294, 500, and 698 K) eight spectra have been recorded at a pressure around 5 mbar and for an absorption path of about 190 cm−1 using a Bomen DA3 Fourier transform spectrometer (4 × 10−3 cm−1 resolution). Some of the measured positions and intensities can be compared with recent experimental results that validate the experimental set-up and the data analysis procedure. The results are also compared with the values listed in the HITRAN 2000 database. If the agreement is generally good, discrepancies are observed for three hot bands. |
