| 英文摘要 | the dissociation dynamics of hfco(+) ion has been studied using the velocity map ion imaging technique. the hfco(+) ion is prepared by one-photon resonant three-photon ionization in the region of 43100-43860 cm(-1) excitation energy. the hfco(+) ions, produced by multiphoton ionization, have sufficient internal energy to dissociate into the f and hco(+) fragments without further absorption of another photon. images of hco(+) have been recorded at various excitation energies. it is noticed that the angular distributions of hco(+) change dramatically from parallel distribution to perpendicular distribution and then back to parallel distribution in a very narrow excitation energy region of 43 473-43 500 cm(-1). analysis of anisotropy parameters of beta(n) (n = 2, 4 and 6) reveals that the electronic states in the three-photon excitation of hfco are mainly: hfco(x'a') -> hfco(a(1)a '') -> hfco(a') - hfco(+)(a(2)a '';b(2)a'). the purely perpendicular resonant transitions are likely responsible for the perpendicular angular distribution of the hco(+) ion fragment. |
