Photodissociation of NaK: Ab Initio Spin-Orbit Interactions of the Na (3 ~2S) K (4 ~2P_J) Manifold

摘要

The relevant interstate b~3#PI#, A~1#SIGMA#~+, c~3#SIGMA#~+, and B~1#PI# spin-orbit induced matrix elements, arising from the Na (3 ~2S) K (4 ~2P_J) manifold are treated within the full microscopic Breit-Pauli approximation based on ab initio configuration interaction (CI) Wave functions. The determination of these couplings as a function of the internuclear distance of NaK should permit a full treatment of the fine treatment of the fine-structure branching ratio K~*(4 ~2P_(1/2)(D_1))/K~*(4 ~2P_(3/2)(D_2)) in manifold-mediated photodissociation and in the treatment of interstate perturbations.
