摘要：
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 mum and the corresponding spectral parameters (i.e. positions, intensities, self-broadening coefficients) are presented. The intensity of the weakest line detected is 2.25163 x 10(-27) cm(-1)/(molecule(.)cm(-2)) at the pressure of 5 Torr, with a corresponding absorption of 3.88 x 10(-8).
