Molecular Electronic Structure via Photoelectron Imaging Spectroscopy
This dissertation explores the use of photoelectron imaging spectrometry to probe the molecular electronic structure of various chemical systems, with an emphasis on photoelectron angular distributions. Experimental ion generation, mass selection, laser photodetachment, and photoelectron ion …

Photoelectron Imaging of Iodide Centered Alkyl Halide Cluster Anions
… Cl) detachment. The experimental cluster anion photoelectron angular distribution trends deviate somewhat from the ab initio calculations and experimental electron scattering data. A discussion follows, wherein these deviations are attributed to the incident electron angular momentum and …

Exploring the Chemistry of Methoxide with Oxygen through Photoelectron Imaging Spectroscopy
In this dissertation, photoelectron imaging spectroscopy is employed to probe the gas-phase chemistry between methoxide (CH3O) and oxygen, including evidence of previously unexplored reaction paths and providing further insight into the fundamentals of chemical bonding. First, the known reaction …

Photoinitiated Dynamics of Cluster Anions via Photoelectron Imaging and Photofragment Mass Spectrometry
… these competing processes by means of photoelectron imaging spectroscopy combined with tandem time-of-flight (TOF) mass spectrometry. Photoelectron images are reported for members of the [(CO2)n(H2O)m]- cluster series. For homogeneous solvation, the photodetachment bands show evidence …

Development and Construction of a new Photoelectron Imaging Spectrometer for Studying the Spectroscopy and Ultrafast Dynamics of Molecular Anions
… time-of-flight mass spectrometer; and a compact photoelectron imaging arrangement for anions, which negates the use of pulsed high voltages. We use this instrument in conjunction with a femtosecond laser system to perform the first ultrafast time-resolved photoelectron imaging experiments on …

Exotic Species of Hydrogen
… path integral formalism. We employ a new kind of photoelectron imaging that maps continuous wavefunctions generated from a fast atomic beam in the focal area of an intense laser onto a 2D detector. The method permits a full reconstruction of the wavefunction by means of numerical inversion of the …

Effects of Anion Excited States on Photodetachment of Negative Ions
… change in photodetachment cross section and photoelectron agular distribution) is observed for diatomic (AgF<super>-</super>, CuF<super>-</super>) and triatomic (NiO<sub>2</sub><super>-</super>, CuOF<super>-</super>) anions. The mechanism of the autodetachment (vibrational or electronic …
