Analysis of the 2ν1+ ν2+ 2ν3Band of Ozone

Determination of the Effective Ground State Potential Energy Function of Ozone from High-Resolution Infrared Spectra

“…These band centers were determined indirectly from small perturbations exerted on the upper states of other very weak bands, and no single line of the (000)-(321) and (000)-(024) bands was directly observed (47,54). In view of this, the agreement between theory and experiment for the "dark" states of Table 3 is very satisfactory.…”

“…The relatively large discrepancies of 3.3 and 1.5 cm Ϫ1 in Table 3 correspond to the maximum experimental uncertainties for the band centers considered here, estimated as ␦ obs ϭ 2.5 cm Ϫ1 and ␦ obs ϭ 3.2 cm Ϫ1 for the (321) and (024) bands, respectively (47,54). These band centers were determined indirectly from small perturbations exerted on the upper states of other very weak bands, and no single line of the (000)-(321) and (000)-(024) bands was directly observed (47,54).…”

“…(45). Sixteen "dark" states corresponding to "shadow" bands are currently available in the literature (42,44,47,48,50,51,(53)(54)(55)(56).…”

Infrared Spectrum of Ozone in the 4600 and 5300 cm−1Regions: High Order Accidental Resonances through the Analysis of ν1+ 2ν2+ 3ν3− ν2, ν1+ 2ν2+ 3ν3, and 4ν1+ ν3Bands

“…As in Refs. (38,39), we report in Tables 3 and 4 an estimate of the uncertainty d for the parameters of the (330) and (024) states which takes into account this lack of information and the extrapolation of the other spectroscopic constants. For these reasons we have fitted separately the observed spectra using approximate effective Hamiltonians for two dyads (Table 1) which involve the (123)/(330) and the (401)/ (024) states, respectively.…”

Line Positions and Intensities of the ν1+ ν2+ 3ν3, ν2+ 4ν3, and 3ν1+ 2ν2Bands of Ozone

“…assign transitions corresponding to values of K a up to 8 for the Starting from extrapolated rotational constants and band centers (014) state. The next step has permitted us to assign all the (20), we have performed a first calculation for the n 1 / n 2 / lines corresponding to the n 2 / 4n 3 band. We give in Fig.…”
