摘要: Fifteen new absorption lines were observed when studying CO2 absorption spectroscopy by wavelength modulation technique with a distributed feedback laser. The overtone spectra of CO2 around 1.31μm and the corresponding spectral parameters (i.e. positions, intensities, self-broadening coefficients) are presented. The intensity of the weakest line detected is 2.25163×10-27cm-1/(molecule·cm-2) at the pressure of 667Pa, with a corresponding absorption of 3.88×10-8.
