The dissociative ionization and the Coulomb explosion of CH3I irradiated by a 35 fs 800 nm laser with a laser intensity of 4 x 10(13) to 6 x 10(14) W/cm(2) was studied. in a relatively weak laser field (about 10(13) W/cm(2)), the dissociative ionization of CH3I took place. The speed distributions of the CH3(+) and I+ fragments were measured and fitted using multiple Gaussian functions. Different product channels were found for CH3+ and I+, respectively. In a strong laser field (about 10(14) W/cm(2)), the multiply ionized fragment ions of Iq+ (q
