The evolution of the electronic structure of {ital V}{sub {ital n}} clusters is probed by photoelectron spectroscopy (PES) at 3.49, 4.66, and 6.42eV photon energies. Three regions of spectral evolution are distinctly observed as a function of cluster size: molecularlike behavior for {ital n}=3{endash}12; transition from molecular to bulklike for {ital n}=13{endash}17; gradual convergence to bulk for {ital n}{approx_gt}17, for which a surfacelike feature is observed to slowly merge into the bulk feature near {ital n}=60. The PES spectra provide an atom-by-atom view of the evolution of the electronic structure of the V{sub {ital n}} clusters from molecular to bulklike. {copyright} {ital 1996 The American Physical Society.}
