THE 3.3-MU-M-BANDS OF OZONE - LINE POSITIONS AND INTENSITIES

The analysis of high-resolution (0.010 cm-1) Fourier transform spectra of 16O3 has provided an extensive set of rotational energy levels belonging to the (003), (102), and (201) vibrational states of this molecule. These experimental energy levels were then satisfactorily reproduced with a Hamiltonian taking explicitly into account the various resonances (Coriolis and Darling-Dennison) affecting the levels, and precise vibrational energies and rotational and coupling constants were determined. In particular, the following band centers were derived: ν0(003) = 3046.0882, ν0(102) = 3083.7024, ν0(201) = 3186.4097 cm-1. Also, line intensities were measured with an accuracy of about 3% for the strongest lines and satisfactorily reproduced with suitable transition moment operators expanded with respect to rotational operators. Finally, an extensive list of line positions, intensities, and lower state energy levels was generated for the 3ν3, ν1 + 2ν3, and 2ν1 + ν3 bands of 16O3. © 1990.
