Intensities, collision-broadened half-widths, and collision-induced line shifts in the second overtone band of [formula omitted

Abstract

Absolute intensities, self-broadened half-widths, air-broadened half-widths, self-induced and air-induced line shifts were measured in the second overtone (3-0) band of 12 C 16 O at 298 K using a Fourier-transform spectrometer and a multi-spectral-line-fitting technique. The absolute intensity of the band was determined to be (4.62±0.06)×10 −22 cm molecule −1 . The square of the transition moment, | μ 0| 2, of this band was deduced to be (1.712±0.004)×10 −7 Debye 2 . Herman–Wallis factors were estimated to be C=(1.185±0.009)×10 −2 and D=(1.014±0.069)×10 4. While the line widths were nearly the same as those in the 1-0 and 2-0 bands in both of the cases of broadening studied, the collision-induced line shifts were found to be much larger in the 3-0 band.
