Abstract
The absorption spectrum of ozone, 16O3, has been recorded in the 5903-5960 cmâ1 region by high sensitivity CW-cavity ring down spectroscopy (αmin â¼Â 5 Ã 10â10 cmâ1). The ν1 + 3ν2 + 3ν3 and 4ν1 + ν2 + ν3 A-type bands centred at 5919.15 and 5947.07 cmâ1 were newly observed. A set of 173 and 168 energy levels could be experimentally determined for the (1 3 3) and (4 1 1) states, respectively. Except for a few Ka = 5 levels of the (4 1 1) state, the rotational structure of the two states was found mostly unperturbed. The spectroscopic parameters were determined from a fit of the corresponding line positions by considering the (1 3 3) and (4 1 1) states as isolated. The determined effective Hamiltonian and transition moment operators were used to generate a list of 785 transitions given as Supplementary Material.
