Transition metal clusters are produced in molecular beams with laser vaporization of metal targets. Vibrationally and rotationally resolved electronic spectra of the metal clusters are obtained with zero electron kinetic energy (ZEKE) photoelectron spectroscopy. The resolution of the spectra is of the order of sub-millielectron volts. Experiments on bare vanadium and yttrium clusters and ligated yttrium, zirconium, and niobium clusters are presented. The bond length of vanadium dimer is determined from the rotationally resolved spectra. Electronic states and molecular geometries of larger clusters are determined by combining the vibrationally resolved spectra with density functional theory and Franck-Condon factor calculations.
