STUDY OF THE LIZN EXCIMER - BLUE GREEN BANDS

We performed a study of the LiZn excimer formed in the photochemical reaction of Li2 (C 1-PI(u)) with Zn (4 S-1(0)). The Li-2 (C 1-PI(u) molecules were prepared by excitation with either a dye laser in the region from 348 to 377 nm or an excimer laser at 308 nm. We observed bound-free emission of LiZn at 477 nm. Nonrelativistic ab initio calculations of the potential energy curves and the relevant dipole transition moments have been performed. Using these results in spectral simulations the observed emission is interpreted as belonging to the 2 2-PI-X 2-SIGMA+ transition of the LiZn molecule.
