摘要：
The IR absorption spectra of pure carbon dioxide in the region of the forbidden v(2) + v(3) vibrational transition at 3004 cm(-1) have been recorded using a Fourier-transform spectrometer. A multipass-optical cell with the path length of 100 m was used in the study. The data were taken at room temperature of 294.8 K with a resolution of 0.02 cm(-1) over the spectral region 2500-3500 cm(-1). A sample pressures varied from 207 to 463 kPa (2.04-4.57 atm). The measured binary absorption coefficients provide the band integrated intensity value of (2.39 +/- 0.04) (*) 10(-4) cm(-2) amagat(-2). The result is compared with those from previous works. The observed band profile features are discussed. (C) 2017 Elsevier Inc. All rights reserved.
