Abstract

Abstract

Using a laser longpath experimental system which White cell with CO2 of 80 or 40 kPa, the highresolution absorption spectra of CO2 near 1.315μm have been recorded and the spectroscopic line parameters are obtained. They are comparable with the data in HITRAN 2k. The absolute absorption is determined by means of path differencing. The total absorption cross section is (0.23~0.29)×10-24cm2 for CO2 at 7 603.138 5cm-1, and the absorption cross section comes of the spectroscopic lines is 0.18×10-24cm2. There is continuum absorption in this region and the continuum absorption cross section is (0.05~0.11) ×10-24cm2. The error is discussed as well.
