| 英文摘要 | the predissociation dynamics of nitrous oxide ion (n2o+) at its first excited state a (2)sigma(+) has been investigated with ion velocity imaging by probing the no+ fragments. the parent ion n2o+, prepared at the ground state x-2 pi(000) through (3+1) resonance-enhanced multiphoton ionization (rempi) of jet-cooled n2o molecules at 360.55 nm, was excited to different vibrational levels of the a (2)sigma(+) state in a wavelength range of 280320 nm, and then predissociated to form no+ and n fragments. the internal energy distribution of the no+ fragment was determined from its ion velocity images. with the help of potential energy surfaces (pess) of n2o+, three dissociation pathways have been proposed to interpret the three kinds of no+ fragments with different internal state distributions: (1) the a (2)sigma(+) state couples to a dissociative 1(4)sigma(-) state via a bound 1 (4)sigma(-) state to form the no++n(4s) channel, where no+ fragment is rotationally hot; (2) the a (2)sigma(+) state couples to dissociative states (2)sigma-/(2)delta via the 1 (4)pi state to form the no++n(2d) channel, where no+ fragment is also rotationally hot; (3) the a (2)sigma(+) state couples to the high energy region of the ground state x (2)pi and then dissociates to form the no++n(2d) channel, where no+ is rotationally cold.
