Three-body photodissociation dynamics of I2-(CO2)

► Fast beam photodissociation study of I2-(CO2) by making time and position sensitive measurements of coincident photofragments. ► Rare example of vibrationally-resolved, three body translational energy distributions. ► Direct measurement of I2-(CO2) binding energy. ► Asynchronous-concerted decay mechanism evidenced through Dalitz plot analysis.
