| 英文摘要 | oxygen-poor vanadium oxide clusters, v2on+ (n=1, 2), v3on+ (n=1, 2, 3), and v4o3+, were produced by laser vaporization and were mass-selected and photodissociated with 532 and 266 nm photons. the geometric structures and possible dissociation channels of these clusters were determined based on the comparison of density functional calculations and photodissociation experiments. the experiments show that the dissociation of v2o+; v2o2+, and v3o3+ mainly occurs by loss of vo, while the dissociation of v3o+ and v4o3+ mainly occurs by loss of v atom. for the dissociation of v3o2+, the vo loss channel is slightly dominant compared to the v loss channel. the combination of experimental results and theoretical calculations suggests that the v loss channels of v3o+ and v4o3+ are single photon processes at both 532 and 266 nm. the vo loss channels of v2o2+ and v3o3+ are multiple-photon processes at both 532 and 266 nm. |
