Abstract
The Coulomb Explosion Imaging technique is used to study cis- and trans-dichloroethene molecules in the gas phase. The molecules are photo-ionized by 790nm, 25fs 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. This method is used to calculate the kinetic energy released after the molecule has been photo-ionized.
