Photodissociation of HBr in and on Arn Clusters: The Role of the Position of the Molecule.

Original language description

Photodissociation experiments are carried out for single HBr molecules which areembedded in the interior or absorbed on the surface of large Ar$_n$ clusters.For the embedded case the size dependence is measured for the average sizesn=51, 139, 230, 290, and 450. For the surface case and the average sizen=139 the cluster temperature is varied by changing the source temperature fromT=163 K to 263 K. The measured kinetic energy of the H atom fragments is measuredexhibiting peaks at zero and 1.3 eV which mark completely caged and unperturbedfragments, respectively. The results are compared with Molecular Dynamics simulationswhich account for the quantum librational delocalization of the HBr molecule. The location of the molecule in/on the cluster is obtained from a trajectory study of the pick-upprocess under realistic conditions. For the embedded case corresponding to aco-expansion experiment, three argon layers are sufficient to completely hinderthe H atom.
