✦ Synopsis

The photodissociation of CBrCls at 248 nm has been studied by translational spectroscopy. The primary dissociation process is shown to produce exclusively CC& and Br with an average translational energy of 20 kcal/mol. From the measured anisotropy parameter /I= -0.4f0.2, CBrCls undergoes a simple C-Br bond scission after excitation via an EtAr transition polarized perpendicular to this bond. A secondary dissociation process from CCls by absorbing an additional photon is also observed at high laser powers.
