“…Similar to the situation with (014) (see the previous paragraph), the hot band ν1 + 4ν3 − ν3 in the range of 3820-3900 cm −1 was analyzed to identify the lines belonging to the upper state (104). The analyses of the 2ν 1 + ν 2 + 2ν 3 (4700-4840 cm −1 ) [203], 2ν 1 + 3ν 3 (5000-5100 cm −1 ) [205], ν 1 + 2ν 2 + 3ν 3 , 4ν 1 + ν 3 (5250-5350 cm −1 ) [206], and 2ν 1 + ν 2 + 3ν 3 (5480-5530 cm −1 ) [207] bands were carried out within the framework of the dyad of interacting states. The integrated intensities of all these bands are less than 1 × 10 −22 cm/molecule (except for the 2ν 1 + 3ν 3 band).…”

The first part of this review is a brief reminder of general information concerning atmospheric ozone, particularly related to its formation, destruction, observations of its decrease in the stratosphere, and its increase in the troposphere as a result of anthropogenic actions and solutions. A few words are said about the abandonment of the Airbus project Alliance, which was expected to be the substitute of the supersonic Concorde. This project is over due to the theoretical evaluation of the impact of a fleet in the stratosphere and has been replaced by the A380, which is now operating. The largest part is devoted to calculations and observations of the transitions in the infrared range and their applications for the atmosphere based both on effective models (Hamiltonian, symmetry rules, and dipole moments) and ab initio calculations. The complementarities of the two approaches are clearly demonstrated, particularly for the creation of an exhaustive line list consisting of more than 300,000 lines reaching experimental accuracies (from 0.00004 to 0.001 cm−1) for positions and a sub percent for the intensities in the 10 microns region. This contributes to definitively resolving the issue of the observed discrepancies between line intensity data in different spectral regions: between the infrared and ultraviolet ranges, on the one hand, and between 10 and 5 microns on the other hand. The following section is devoted to the application of recent work to improve the knowledge about the behavior of potential function at high energies. A controversial issue related to the shape of the potential function in the transition state range near the dissociation is discussed.
