Metal-organic radicals are reactive and transient because of the existence of unpaired valence electrons, and thus the characterization of these open-shell systems is challenging. In our work, the radicals are synthesized by the reaction of bare metal atoms and organic ligands in a laser-vaporization supersonic molecular beam source and characterized with pulsed-field ionization zero electron kinetic energy (ZEKE) spectroscopy. The molecular beam ZEKE technique routinely yields sub-meV spectral resolution and is a powerful means to study the molecular bonding and structures. This account presents several examples of single-photon ZEKE spectroscopic applications in determining metal binding modes and molecular conformations.
