Electronic properties and geometric structures of Li4H and Li9H from optical absorption spectra

摘要: Optical absorption spectra of Li4H and Li9H clusters have been recorded by depletion spectroscopy in the visible range. From comparison with ab initio calculations, geometries both are identified. The hydrogen atom assumes a peripheral position bridging two three Li atoms planar three‐dimensional structures Li9H, respectively. Na4F Na9F also theoretically studied it is shown how strong electronegativity F leads to different than lithium hydrids. Finally, metallic character these discussed cases, or fluorine localizes one valence electron. However, optical much broader pure Lin Nan due lower symmetry.
