Abstract
The nascent population distribution of LiH (ν=0) was observed in the endothermic reaction of Li(2 2Pj) with a H2. The rotational distribution was similar to those formed by the K, Rb, and Cs reactions with H2. The result differed in case of Na which yielded a bimodal distribution. The potential energy surface (PES) calculations showed side-on attack of Li insertion into the H-H bond. The reaction barrier of 1280 cm-1, calculated from temperature dependence measurements, was equivalent to the endothermicity of the system. The dynamic behavior of Li(32P) state was also investigated.
