THE 10$\mu m$ BANDS OF THE $^{17}O_{3}$ ISOTOPIC SPECIES OF OZONE:

Abstract

Using Fourier transform spectra recorded at LPMA ($\mathcal{R} \sim 0.002 cm^{-1}, P=0.3, 0.5$ and 0.9 torr, L-1.15m) of $\sim 64% ^{17}O$-enriched ozone, it has been possible to assign the ($\nu_{1} \nu_{3}$) bands of $^{17}O_{3}$ up to very high rotational quantum numbers. For this analysis, we used the ground state energy levels calculated from the (000) rotational constants obtained for $^{17}O_{3}$ in a recent microwave study performed by Colmot et $al.^{(1)}$. Then, from the set of {(100),(001)} rotational energy levels derived in this work, a set of molecular parameters (vibrational band centers, rotational and coupling constants) for the {(100),(001)} interacting states has been determined using a Hamiltonian matrix which takes explicitly into account the $(100)<->(001)$ Coriolis-type interaction operator. Finally, using $\nu_{1}$ and $\nu_{3}$ theoretically derived calculated transition moment operators, a synthetic spectrum (line positions and intensities) of the $\nu_{1}$ and $\nu_{3}$ bands has been generated.
