The simplest alkali metal acetylides MCCH were made in the gas phase for the first time (see drawing), and their bond lengths were determined by millimeter/submillimeter spectroscopy of their isotopomers. The M-C bond lengths r are the shortest known for organoalkali metal compounds. In the case of

✦ Synopsis
A coupled-cluster study of LiCCH is presented to provide state-of-the-art calculations for the equilibrium geometry of LiCCH and to supply vibration-rotation interaction constants, thus making possible the determination of an r e structure based on rotational constants from a recent microwave investigation of various isotopomers of LiCCH. The power of this combined experimental and theoretical approach to accurate equilibrium geometries is emphasized.
