Notes:
The existence of the stable lithium cluster Li5 has been proved experimentally by mass spectrometry. From the measurement of the gaseous equilibria Li5(g)+Li2(g)=Li4(g)+Li3(g) and Li5(g)+Li(g)=Li4(g)+Li2(g), an atomization energy D00(Li5) =110.0±2.5 kcal/mol was obtained. The ionization potential (IP) of Li5(g) was determined as IP(Li5)=4.56±0.3 eV, from which the atomization energy of the molecule ion Li+5, D00(Li+5) =130.0±5.0 kcal/mol is obtained for the reaction Li+5→Li++4 Li. The heat of formation was determined as ΔH00(Li5) =82.5±2.0 kcal/mol. By extrapolation from experimental results, the properties of neutral and ion clusters of hexamer lithium Li6 were predicted.
