Abstract
The ratio of the populations of $Cl(^{2}P_{1/2})$ to $Cl(^{2}P_{3/2})$ produced in the photodissociation of HCl was measured as a function of excitation energy. Three photons were used to excite HCl to the $A'\Pi$ continuum state, while two photons were used to populate ten predissociating Rydberg states Multi-photon velocity-aligned Doppler spectroscopy was used to characterize the energetics and symmetry of the two-photon transitions. The $A^{1}\Pi$ results will be compared with the calculations of $Alexander et. al.^{1}$ and Givertz and $Balint-Kurti^{2}$. The Rydberg states displayed complex behavior. Some of the states gave a statistical branching ratio, others yielded primarily $Cl(^{2}P_{3/2})$, while still others gave comparable amounts of both Cl states. In some cases the branching ratio varied with rotational angular momentum.
