Photodissociation of oriented HXel molecules in the gas phase

摘要

We report the first production of the molecle HXeI, which is bound by ionic forces, in the gas phase. The molecle is generated by the photodissociation of HI molecules on a large Xe_n cluster and is identified by detecting the asymmetric distributionof the H atom fragments of the oriented HXeI. The orientation is achieved in a combined pulsed laser and weak electostatic field making use of the large anisotropy in the polarizability and the large dipole moment of this molecule.
