Control of the photodissociation of CH2BrCl using a few-cycle IR driving laser pulse and a UV control pulse
Control of the non-adiabatic photodissociation dynamics of CH2BrCl into CH2Br + Cl or CH2Cl + Br has been achieved using a driving few-cycle IR laser pulse followed by a control UV pulse. Employing two-dimensional time-dependent wave packet propagations on a three-state diabatic model we show that the branching ratio leading to the dissociation of the stronger bond ( C-Cl) can be increased by an order of magnitude.
