High-resolution photoelectron spectroscopy of metal clusters and high-temperature species

This dissertation investigates the high resolution photoelectron spectroscopy of metal clusters and high temperature species. A high temperature molecular beam source has been built. High temperature species and group V element clusters have been measured with 12-15 meV resolution. Vibrational structure is resolved and fundamental spectroscopic constants are obtained. Information about the electronic structure and chemical bonding is derived.;Chapter 3 presents the vibrationally-resolved photoelectron spectra of the heavy group IV-VI diatomics. Relativistic effects play an important role in these heavy diatomics, resulting in avoided curve crossings in the ;Chapter 5 describes the experiments on the group V element clusters. Vibrational structure is resolved explicitly for As;Chapter 6 deals with the high resolution photoelectron spectra of ZnCl...
