    Cs(6D3/2)+H2→CsH+H reaction. IV. Rotationally resolved total cross sections (1999)

    Notes: The Cs(6D3/2)+H2→CsH [X 1Σ+(v″=0,1; J″)]+H photochemical reaction has been studied in a crossed-beam experiment with electronic excitation of Cs atoms and laser-induced fluorescence detection of CsH products. The reactive cross section is measured at a collision energy of 0.09 eV: σ(6D3/2)=0.04×10−16 cm2. The rotational distributions of CsH products measured on v″=0 for 0≤J″≤23 and on v″=1 for 0≤J″≤15 are close to statistical ones with 16% of products in v″=1. A quasi-classical 3D trajectory calculation of this reaction yields both rotational and vibrational distributions of CsH products and their angular scattering probability. The reactive cross section measured with Cs(6D3/2) excitation is an order of magnitude smaller than the cross section σ(7P1/2)=0.6×10−16 cm2, which is re-evaluated in this article. © 1999 American Institute of Physics.

    The Sc+NO→ScO+N reaction: Rotational state distribution in ScOX 2Σ+(v″=0) (2001)

    Notes: The Sc+NO→ScO+N reaction has been investigated in a beam-gas arrangement, with characterization of ScO products by cw laser-induced fluorescence: absorption versus laser frequency over the A 2Π(v′=1)–X 2Σ+(v″=0) band and fluorescence over the A 2Π(v′=1)–X 2Σ+(v″=1) one. It leads to the direct determination of the nascent rotational state distribution in the X 2Σ+(v″=0) level of ScO. This distribution is close to a Prior statistical one, with a well-characterized weak "surprisal," indicating that a momentum constraint takes place during the reaction process. In the frame of this statistical distribution, a new accurate value for the dissociation energy of ScO is proposed: D00(ScO)=(6.92±0.01) eV. Spectroscopic data are reported for the A 2Π(v′=1)–X 2Σ+(v=0) band, up to N=98. © 2001 American Institute of Physics.

    A full description of the potential curve of the B 1Πu state of 7Li2 (2001)
    College Park, Md. : American Institute of Physics (AIP)

    Notes: An accurate potential curve for the bound and quasibound region of the B 1Πu state of 7Li2 is produced by analyzing high resolution sub-Doppler B 1Πu←X 1Σg+ excitation spectra in conjunction with lower resolution data of Hessel and Vidal [J. Chem. Phys. 70, 4439 (1979)] and of Russier et al. [J. Mol. Spectrosc. 168, 39 (1994)]. The bound and quasibound part of the curve is generated by the direct fit of molecular energies to a numerical potential; the outermost (repulsive) part of the curve is calculated by an asymptotic method using Coulombic and exchange parameters determined from the 1 1Πg and A 1Σu+ states of the lithium dimer. The full potential energy curve of the B 1Πu state reproduces all measured energies of f parity, and the widths of the predissociated lines, to within the experimental accuracy. © 2001 American Institute of Physics.
