Comparing with the result of methyl iodide in intense laser field, some differences are observed:(1) at the same laser field intensity, the highest charged fragment ion of methyl bromide was Br(superscript 3+), lower than I(superscript 6+) of methyl iodide;(2) the dehydrogenation channel was observed in the multiphoton dissociation or Coulomb explosion of methyl bromide, but was not observed in the case of methyl iodide;(3) HBr(superscript +) was observed, but there was no similar channel in the case of methyl iodide;(4) for methyl bromide, the valid charge distance of Coulomb explosion increases with the product of p and q; while in the case of methyl iodide, the distance remained almost the same;(5) the producing channel of CH(superscript + subscript m)(m=0, 1, 2) is different from the ionization-dissociation of methyl iodide in which the stepwise dissociation of CH3(superscript +) was thought to be the main channel, CH(superscript + subscript m)(m=0, 1, 2) of methyl bromide are mainly from the products of the direct dissociation of the dehydrogenated parent ions instead of the stepwise dissociation of CH3(superscript +).
