✦ Synopsis
A SCF CI smdy of LtH2 mcludmg up IO SO0 determinants is reported. We find no evidence for the stabilization of such a molecule. confirming prex~ous throrcrical results and casung doubr on proposed rxprrrmenral evidence for its mistcnce. Net charge trnnsfcr rrom the hydrogens to Li IS evident along the whole Li(?s"S)+ Hz = LIH, reaction pathway in C2, symmetw. The insertion and absuaclion mechanisms for the formation of LIH + H products from Li + Hz are compared

Ab initio molecular orbltal calculations on the transitton states and barrter heights for the addition of atomtc hydrogen to sllaethylene are carried out. The activation energy for the addition to the silicon site is lower than that to the carbon site, wlnle the exothermicity 1s smaller.
