Abstract
We measured at 296 K the rotational line strengths and pressure-broadening coefficients for the 1.27-μm, a1Δg–X3Σg−, v = 0–0 band of O2 with a Fourier transform infrared spectrometer using an optical path length of 84 m, a spectral resolution of 0.01 cm−1, and sample pressures between 13 and 104 kPa. The integrated band strength is 7.79(17) × 10−6 m−2 Pa−1 [7.89(17) × 10−5 cm−2 atm−1], and the Einstein Acoefficient for spontaneous emission is 2.237(51) × 10−4 s−1, which corresponds to an upper-state1/e lifetime of 1.24(3) h. The pressure-broadening coefficients decrease with increasing N and range from 19 to 38 MHz/kPa (FWHM). The mean value for the transitions studied is 30.3(21) MHz/kPa [0.1024(71) cm−1/atm] (FWHM). The Einstein A coefficient determined here is in good agreement with the widely accepted value of 2.58 × 10−4 s−1 initially obtained by Badgeret al. [J. Chem. Phys. 43, 4345 (1965)] more than 30 years ago. The standard uncertainties given above are one standard deviation.
