title: High-Resolution Infrared, Microwave, and Submillimeter-Wave Study of FClO(2) in the nu(2), nu(3), nu(4), and nu(6) Excited States.
abstract: A high-resolution analysis of the {nu(2), nu(3)} and {nu(4), nu(6)} bands of the two isotopomers of chloryl fluoride F(35)ClO(2) and F(37)ClO(2) has been carried out for the first time using simultaneously infrared spectra recorded around 16&mgr;m and 26&mgr;m with a resolution of ca. 0.003 cm(-1) and microwave and submillimeter-wave transitions occurring within the vibrational states 2(1), 3(1), 4(1), and 6(1). Taking into account the Coriolis resonances which link the rotational levels of the {2(1), 3(1)} and the {4(1), 6(1)} interacting states, it was possible to reproduce very satisfactorily the observed transitions and to determine accurate vibrational energies and rotational constants for the upper states 2(1), 3(1), 4(1), and 6(1) of both the (35)Cl and (37)Cl isotopic species.
