| 英文摘要 | photodissociation dynamics of the h-atom channel from hnco photolysis between 124 and 137 nm have been studied using the h-atom rydberg tagging time-of-flight technique. product translational energy distributions and angular distributions have been determined. two dissociation channels, h + nco (x-2 pi) and h + nco(a(2)sigma(+)), have been observed. the former channel involves two different dissociation pathways; one is a slow predissociation pathway through internal conversion from the excited state to the so state, and the other is a fast predissociation pathway through internal conversion from the excited state to the s, state. the latter channel dominates by a prompt dissociation via coupling to the s-2 state. as the photon energy increases, dissociation on the ground state s-0 becomes dominant. vibrational structures are observed in both the nco(x) and nco(a) channels, which can be assigned to the bending mode excitation with some stretching vibrational excitation. |
