THE HYBRID-TYPE BANDS NU-1 AND NU-3 OF O-16 O-16 O-17 LINE POSITIONS AND INTENSITIES

A study of 0.005 cm-1 resolution room temperature absorption spectra of 17O-enriched ozone around 10 μm has been performed leading to a thorough analysis of the hybrid ν1 and ν3 bands of 16O16O17O. The experimental rotational levels af the interacting states (001) and (100) were reproduced using a Hamiltonian taking fully into account the rovibratianal interactions. Precise vibrational energies and rotational and coupling constants were deduced and the following band centers were determined: ν0(ν1) = 1095.69309 cm-1 and ν0(ν3) = 1035.35869 cm-1. Using the 16O17O16O line intensities calculated previously and assuming a factor of 2 between the abundances of 16O16O17O and 16O17O16O, the amount of 16O16O17O in the cell was evaluated and used to derive the line intensities for this latter species. Then the experimental intensities were least squares fitted, leading to the determination of the transition moment constants of the ν1 and ν3 bands of 16O16O17O. Finally a complete spectrum of these bands has been computed. © 1993 Academic Press, Inc.
