Unimolecular dissociation dynamics of highly vibrationally excited DCO(X̃ 2A). II. Calculation of resonance energies and widths and comparison with high-resolution spectroscopic data
The authors present a theor. study of the unimol. dissocn. of DCO in the electronic ground state, $\sim$X¹A', using a new ab initio potential energy surface. Altogether the authors analyzed ‚àº140 resonances up to an energy of ‚âà1.4 eV above the D+CO threshold, corresponding to the ninth overtone in the CO stretching mode (v2 = 9). The agreement of the resonance positions and widths with recent stimulated emission pumping measurements of Stoeck et al. [J. Chem. Phys. 106, 5333(1997), the preceding article] is pleasing. The root-mean-square deviation from the exptl. energies is only 16 cm-1 over a range of ‚àº16,500 cm-1 and all trends of the resonance widths obsd. in the expt. are satisfactorily reproduced by the calcns. A strong 1:1:2 stretch-stretch-bend resonance prohibits a unique assignment for the majority of vibrational states. [on SciFinder(R)]
