THE LIHG(2(2)PI(3 2)-X(2)SIGMA(+)(1/2)) SYSTEM/

We report the determination of the complete LiHg shallow bound ground state potential curve by combination of laser-induced fluorescence spe ctroscopy of bound-bound transitions, photoassociation spectroscopy of bound-free transitions, and ab initio calculations. The results are e valuated by comparison of quantum mechanically simulated emission spec tra with experimental data and used to describe spectroscopic features of the 2(2) Pi(3/2)-X(2) Sigma(1/2)(+) band as well as the photochemi cal formation via excitation of the lithium dimer.
