Extended Analysis of Line Positions and Intensities of Ozone Bands in the 2900–3400 cm−1 Region

The 2900–3400 cm −1 spectral range is revisited for an accurate determination of line positions and line intensities of the 3ν 3 , ν 1 +2ν 3 , 2ν 1 +ν 3 , and 3ν 1 bands of ozone. The fit on 4520 rotational energy levels of (012), (111), (210), (130), (003), (102), (201), and (300) vibrational states determined from observed transitions of cold and hot bands in the 2400–3400 cm −1 region with J max =65 and K a max =20 gives a r.m.s. =7×10 −4 cm −1 and provides a satisfactory agreement between calculated and observed line positions (dimensionless standard deviation is χ=1.44). The set of 2580 line intensities of 7 rovibrational bands has been measured and fitted with a r.m.s. =6.9% (χ=1.2), leading to the determination of transition moment parameters for these bands. Using these parameters we have obtained more precise estimation for the integrated band intensities S(3ν 3 )=1.41×10 −19 , S(ν 1 +2ν 3 )=1.28×10 −20 , S(2ν 1 +ν 3 )=7.91×10 −21 , S(3ν 1 )=4.72×10 −22 cm −1 /mol cm −2 at 296 K, with a cutoff 2×10 −26 cm −1 /mol cm −2 . The interactions of the tetrad (003)/(102)/(201)/(300) with the (130) state and the tetrad (040)/(012)/(111)/(210) are studied.
