Electron Spectroscopic and Theoretical Investigations of Small Molecules

点击翻译按钮获取中文摘要

In this project in the Physical Chemistry Program of the Chemistry Division, electron spectroscopic studies will be carried out which aim at understanding chemical effects on the behavior of excited molecular complexes. In addition to its intrinsic scientific interest, this research has connections with site-selective X-ray photochemistry and could have applications in nanolithography and future generations of semiconductor device technology. Electron spectroscopy will be used to determine the energies needed to remove inner-shell electrons from small molecules in the gas phase and to study the dynamics and energetics of the processes by which these highly excited molecules lose their energy. Also concerned with the dynamics of inner-shell de-excitation will be a theoretical and experimental study of the effects of molecular environment on the rate of Auger decay in molecules containing carbon, nitrogen, oxygen, and fluorine.
