Intensities, self-broadening, and broadening by Ar and N2 for the 301III ← 000 band of CO2 measured at different temperatures

Intensities and self-broadening coefficients of the CO2 Ro-vibrational transitions measured by a near-IR diode laser spectrometer

“…Toth et al [4] measured the four bands of this Fermi-tetrad by a grating spectrometer, and Suárez and Valero [5][6][7] also observed the same bands by an FTIR spectrometer. Their results carry large experimental error of several percent, and there are systematical difference between the two.…”

“…It should be noted that the uncertainties for the present values do not contain the possible errors due to the pressure uncertainty, which may be 0.5% at most. Suárez and Valero [5][6][7] have observed four Fermitetrad bands by an FTIR spectrometer. Their S values are similar to the recent laser study by Pouchet et al [10] who have observed the m 1 + 4m 2 + m 3 band by a diode laser spectrometer.…”

“…In Table 1, some results found in literature are also listed. The earliest two studies were published in 1970Õs by Toth et al [4] and Suárez and Valero [7]. Toth et al have measured the four Fermi-tetrad bands by a grating spectrometer and reported S values, but these values have large error of $3.5%.…”

“…The values listed here are the ones for the same m in the 2m 1 + 2m 2 + m 3 band is by 120 cm À1 higher than the m 1 + 4m 2 + m 3 band. study by Suárez and Valero [7] have large experimental uncertainties. The c L values of recent FTIR work by Fukabori et al [8,9], are slightly larger than both our results and HITRANÕs.…”

12C16O2 line intensity measurements around 1.6μm

“…Energy level values were reinvestigated recently by Miller and Brown [5], leading to very accurate absolute line positions (uncertainty 6 · 10 À5 cm À1 ) now available from HITRAN [3]. Individual line intensities in the cold bands were primarily measured by Toth et al [6], and reinvestigated by Suárez and Valero [7][8][9]. Intensities of R-branch lines, and of small J P-branch lines, in the 30012-00001 band, were then obtained by Henningsen and Simonsen [10] by tunable diode laser spectroscopy (TDLS).…”
