(CO2)-C-12-O-16 LINE-INTENSITIES IN THE 4.8-MU-M SPECTRAL REGION

In the 4.8 mu m spectral region, intensities of lines belonging to the 3 following perpendicular bands of (CO2)-C-12-O-16 have been measured : the Pi <-- Sigma cold band 11101-00001 centered at 2076.856 cm(-1), the Delta <-- Pi hot band 12201-01101 centered at 2093.345 cm(-1), and the Sigma <-- Pi hot band 20001-01101 centered at 2129.756 cm(-1). Fo urier transform spectra, under a resolution limit of about 0.0023 cm(- 1), have been used. For each band, the square of the vibrational dipol e-moment matrix element and the Herman-Wallis coefficients have been d etermined. These results are compared with the previous experimental r esults included in the last edition of the HITRAN molecular database, as well as with new results obtained by the Direct Numerical Diagonali zation method.
