The ν1 and ν3 bands of the 16O17O17O isotopomer of ozone

Using 0.002 cm(-1) resolution Fourier transform absorption spectra of an O-17 enriched ozone sample, an extensive analysis of the nu(3) band together with a partial identification of the nu(1) band of the (OOO)-O-16-O-17-O-17 isotopomer of ozone has been performed for the first time. The experimental rotational levels of the (001) and (100) vibrational states could be satisfactorily reproduced using an Hamiltonian matrix which takes into account the observed rovibrational resonances. Actually, as for other C-s-type ozone isotopomers [J.-M. Flaud and R, Bacis, Spectrochimica Acta, A54 (1998) 3-16], the (001) rotational levels are involved in both Coriolis and Fermi type resonances with the levels from the (100) vibrational state. Using an Hamiltonian matrix which rakes explicitly into account these resonances precise vibrational energies and rotational and coupling constants were deduced and the following band centers nu(0)(nu(3)) = 1017.5336 cm(-1) and nu(0)(nu(1)) = 1080.153 cm(-1) were obtained for the nu(3) and nu(1) bands respectively.
