Abstract
The polarization anisotropy of molecular photofragment emission following two‐photon induced dissociation of triatomic molecules is calculated in the high J limit. This theoretical treatment is applied to the two‐photon induced photodissociation of XeF2 at 266 nm from which the XeF B→X emission displays a polarization anisotropy of 3.5%±1.5%. The XeF2 dissociating state is shown to be non‐totally symmetric by measurement of the relative intensities of B→X emission excited by linearly and circularly polarized actinic radiation. Dissociation proceeds via a 1πu Rydberg state.
