The ν2 bands of 16O17O16O and 16O16O17O: Line positions and intensities

Abstract Using a 0.005-cm −1 resolution Fourier transform spectrum of 17 O-enriched ozone, the first extensive analysis of the ν 2 bands of the two isotopic species 16 O 17 O 16 O and 16 O 16 O 17 O 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 v 2 ( 16 O 17 O 16 O) = 697.07934 cm −1 v 2 ( 16 O 16 O 17 O) = 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 ν 2 bands were used to generate a complete list of line positions, intensities, and lower state energy levels for the 16 O 17 O 16 O and 16 O 16 O 17 O isotopic species.
