Photodissociation Dynamics of I− 3: Comparison of Ultrafast Pump Probe Experiments to Raman Scattering

When a UV light pulse is applied to I− 3 in solution, it either absorbs the light leading to fragmentation to I− 2 +I, or scatters the light usually as a Raman process. Since both the fragmentation and the Raman processes are governed by the same ground and excited potential energy surfaces, crossing the information gained from the two independent measurements leads to enhanced insight on the photodissociation event. A unified quantum computational scheme addresses simultaneously the dynamics of photodissociation and the absorption and Raman cross sections.
