摘要We experimentally demonstrate the dissociative ionization of CH2Br2 molecules irritated by 800 and 400 nm femtosecond laser fields using time-of-flight mass spectra and dc-sliced ion imaging technology. Our results show that in both laser fields, CH2Br2 can ionize to CH2Br2+, then CH2Br2+ break one C-Br bond to produce fragments CH2Br(+) and Br(+). The charge assignment is determined by the ionization energy of the fragments. Additionally, in 400 nm laser fields, the CH2Br2+ can overpass a transition state to form an intermediate CH2Br-Br+, then the intermediate break C-Br bond to produce Br-2 or Br-2(+) via elimination channel.
