Abstract:

This report describes results of research directed toward a better understanding of multiphoton ionization MPI processes of molecules expected to have large MPI processes in the near ultraviolet region of the spectrum. The motivation for this work was to develop methods of optically controlling diffuse discharges. During the three-year period of this research, such processes were investigated in a variety of molecules, including NO, the methylamines, ferrocene, SO2, and SO. In addition, some work on the use of photodetachment processes to control diffuse discharges was performed in collaboration with researchers at Texas Tech University, and a Workshop on Optical Control of Diffuse Discharges was held at the University of Oregon. The subsequent sections of this report describes the results of this work. Originator supplied key words include Photoionization, multiphoton, ultraviolet, visible, diffuse discharge, optical control, high current switches, molecules, excited states, molecular spectrscopy, photodetachment, multiphoton dissociation.
