| Abstract: | The N2- and O2-broadening effect have been investigated for 10 absorption lines of the CO2 (3001)III ← (0000) band centered at 6231 cm−1, in the range from P(28) to R(28) by a near-infrared diode-laser spectrometer. We have analyzed the observed line profiles with the Galatry function, and determined the N2- and O2-broadening coefficients precisely. The air-broadening coefficients for these lines have been derived. The present results are compared with those of the previous studies for this band and with some of the other bands. |
