We experimentally studied three-body fragmentation dynamics of (CO2)(2)(3+) generated by intense femtosecond laser fields. Three-dimensional momentum vectors as well as kinetic energies were measured for correlated fragmental ions using the technology of coincidence measurement. The results demonstrate that sequential fragmentation channel dominates for three-body fragmentation of (CO2)(2)(3+), in which the weak van der Waals bond breaks first and then one strong covalent bond.
