High resolution analysis of the 5 nu(3), 3 nu(1)+nu(2)+nu(3), and nu(1)+4 nu(3), bands of O-16(3): Line positions and intensities

Using a Fourier transform spectrum of ozone recorded in the 2.1 mu m region at a resolution of 0.008 cm(-1), it has been possible to perform the first high resolution analysis of the 3v(1) + v(2) + v(3) and 5v(3) bands of O-16(3). These results, together with those derived from the analysis of the v(1) + 4v(3) - v(3) hot band in the 2.5 mu m region, were used to derive a large set of experimental rotational energy levels (up to J = 47 and K-n = 14) for the three vibrational states (005), (311), and (104). These levels were satisfactorily fitted using a Hamiltonian model which takes into account both the anharmonic interactions between the levels of (005) and (311) and the Coriolis-type interactions between the levels of (005) and (104) and of (311) and (104), and a precise set of vibrational energies and rotational and coupling constants was derived. In particular, the following band centers were obtained: v(0) (005) = 4919.2034 cm(-1), v(0) (311) = 4897.2766 cm(-1) v(0)(104) = 4922.5717 cm(-1). Moreover, 126 line intensities were measured and fitted, lending to the determination of transition moment constants for the 3 bands 5v(3), 3v(1) + v(2) + v(3), and v(1) + 4v(3). These constants, together with the Hamiltonian constants derived in this work, were finally used to generate a comprehensive list of line positions and intensities. (C) 1996 Academic Press, Inc.
