The Coulomb Explosion Imaging technique [1,2] is used to study cis- and trans-dichloroethene molecules in the gas phase. The molecules are photo-ionized by 790nm, 25 fs near-infrared laser pulses, and the resulting fragments are measured by coincident ion momentum imaging. The experimental data is then compared to numerical simulations of the Coulomb Explosion process carried out by utilizing the 8th order Runge-Kutta method.
