PHOTODISSOCIATION OF CBRCL3 AT 248 NM BY TRANSLATIONAL SPECTROSCOPY

Abstract

The photodissociation of CBrCl3 at 248 nm has been studied by translational spectroscopy. The primary dissociation process is shown to produce exclusively CCl3 and Br with an average translational energy of 20 kcal/mol. From the measured anisotropy parameter beta=-0.4+/-0.2, CBrCl3 undergoes a simple C-Br bond scission after ''citation via an E<--A1 transition polarized perpendicular to this bond. A secondary dissociation process from CCl3 by absorbing an additional photon is also observed at high laser powers.
