✦ Synopsis

Using a Fourier transform spectrum of ozone recorded in the 2.1 mm region at a resolution of 0.008 cm 01 , it has been possible to perform the first high resolution analysis of the 3n 1 / n 2 / n 3 and 5n 3 bands of 16 O 3 . These results, together with those derived from the analysis of the n 1 / 4n 3 0 n 3 hot band in the 2.5 mm region, were used to derive a large set of experimental rotational energy levels (up to J Å 47 and K a Å 14) for the three vibrational states ( 005), (311), and (104). These levels were satisfactorily fitted using a Hamiltonian model which takes into account both the anharmonic interactions between the levels of ( 005) and ( 311) and the Coriolis-type interactions between the levels of ( 005) and ( 104) and of ( 311) and ( 104), and a precise set of vibrational energies and rotational and coupling constants was derived. In particular, the following band centers were obtained: n 0 (005) Å 4919.2034 cm 01 , n 0 (311) Å 4897.2766 cm 01 , n 0 (104) Å 4922.5717 cm 01 . Moreover, 126 line intensities were measured and fitted, leading to the determination of transition moment constants for the 3 bands 5n 3 , 3n 1 / n 2 / n 3 , and n 1 / 4n 3 . These constants, together with the Hamiltonian constants derived in this work, were finally used to generate a comprehensive list of line positions and intensities.
