Abstract :
Two-body dissociation processes of H2CCH–CH CH 2 2 + induced by an intense laser field were investigated by the coincidence momentum imaging method. Four dissociation pathways, C 4 H 6 2 + → CH2+ + C 3 H 4 + , C 4 H 6 2 + → CH3+ + C 3 H 3 + , C 4 H 6 2 + → C 2 H 3 + + C 2 H 3 + and C 4 H 6 2 + → C 2 H 2 + + C 2 H 4 + , were identified. The existence of the second and fourth pathways can be regarded as evidences of the chemical bond rearrangement processes associated with hydrogen migration in the intense laser field. It was found that the hydrogen atom bonded originally to one of the two central carbon atoms migrates preferentially to its neighboring terminal carbon atom site.
