Abstract

Fifteen new absorption lines are observed when studying CO₂ absorption spectroscopy by wavelength modulation (WM) technique with a distributed feedback laser. The overtone spectra of CO₂ around 1.31 μm and the corresponding spectral parameters (i.e. positions, intensities, self-broadening coefficients) are presented. The intensity of the weakest line detected is 2.25163 × 10^-27 cm^-1/ (molecule·cm^-2) at the pressure of 5 Torr, with a corresponding absorption of 3.88 × 10^-8.
