Resumo: |
This dissertation presents a wavepacket simulation study of the H + HCl collinear reaction when the HCl molecule is initially prepared by an infrared laser pulse in a coherent superposition of vibrational states. A detailed discussion of wavepacket motion, reactive flux and reaction probabilities as function of the superposition state parameters is presented. We apply the flux formalism to derive an analytical expression for the reaction probabilities, which is then used to analyse our numerical simulations. The results show a strong phase dependence of the reaction probabilities, as well as the spatial distribution of the reactant molecules. The full reaction probability surface is computed for two average collision energies, and the enhancement and suppression of the H+HCl!H2+Cl reaction channel is discussed in terms of the surface’s critical points. |
