Photodissociation studies of Cl,-doped Xe in a diamond anvil cell are reported. Excitation of the dissociative `II,+X transition
at 308 nm, leads to complete recombination at 100 K, and 4 GPa. The recombinant emission shows a polarization ratio of 0.95,
indicating that the molecular orientation is preserved to some extent during the process.
1. Introduction
In this Letter, we report the first polarization mea-
surements of recombinant emission in CIZ-doped
solid xenon under high pressure, in a diamond anvil
cell (DAC). The motivation behind the study is en-
trenched in a background of prior experimental and
theoretical studies which we succinctly review before
presenting the data.
The photodissociation of Cl* in rare gas solids is
a model system which may serve as a test of the ex-
tent of our understanding of many-body dynamics.
