THE NU-2-BANDS OF (O3)-O-16-O-17-O-16 AND (O3)-O-16-O-16-O-17 - LINE POSITIONS AND INTENSITIES

Using a 0.005-cm-1 resolution Fourier transform spectrum of 17O-enriched ozone, the first extensive analysis of the ν2 bands of the two isotopic species 16O17O16O and 16O16O17O has been performed. For each isotopic species, the infrared vibration-rotation energies obtained from this analysis together with the available microwave transitions in the ground state were reproduced within their experimental uncertainties using a Watson A-type Hamiltonian. The band centers v2(16O17O16O) = 697.07934 cm-1v2(16O16O17O) = 692.43473 cm-1 were obtained as well as precise rotational and centrifugal distortion constants for both the ground state and the first vibrational state (010) of these two isotopic species. In addition, appropriate expansions of the transformed transition moment operators of the two ν2 bands were used to generate a complete list of line positions, intensities, and lower state energy levels for the 16O17O16O and 16O16O17O isotopic species. © 1991.
