Ionization and dissociation processes of gas molecules, CH2I2 and CH2ICl, in intense femtosecond field (1013-1015 W·cm-2), were investigated by flight time mass spectrometer, irradiated by 60 fs with 800 and 400 nm femtosecond laser. In the moderate intense field, CH2I2 and CH2ICl produced concerted elimination products, I2 and ICl molecules, respectively. The multiple charged ions, I2+, generated in Coulomb explosion under intense femtosecond laser irradiation, split into three peaks in the flight time mass spectra, due to the initial kinetic energies released in the explosion. The C-I internuclear distances during Coulomb explosion and the kinetic energy released were estimated according to the flight time differences.
