We investigated the photochemical formation of lithium-rare-gas excimers in the 32∑+state through the reaction of Li2(2(C)1Πu) and the ground-state rare-gas atom. Lithium-rare-gas vapor mixture was prepared in the heat-pipe oven. We populated the 2(C)1Πustate of the Li2molecule using the XeCl excimer laser wavelength at 308 nm or the PTP dye laser wavelength at about 335 nm. The 32∑+-12∑+transitions were observed with peaks at 4M, 420 and 435 nm for LiAr, LiKr and LiXe, respectively. We estimated thermally averaged rate constants for these photochemical reactions, which are (2.3±1.1)·10-10cm3s-1for LiAr, (6.9±3.2)·10-10cm3s-1for LiKr and (19±9)·10-10cm3s1for LiXe. Ab initio potential-energy curves and transition dipole moments for LiKr were calculated applying the SCF MRDCI method. Available data for the LiAr and LiKr excimers are presented, including potential-energy curves, electronic transition dipole moments, and spectroscopic constants. Possible photochemical formation of these molecules in the excited states is discussed. We performed the quantum-mechanical spectral simulations of the LiAr and LiKr 32∑+-12∑+transitions, using ab initio potential-energy curves.
