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.

在化学部物理化学计划的这个项目中，将进行电子能谱研究，旨在了解受激分子复合物行为的化学效应。除了其内在的科学兴趣外，这项研究还与选择性x射线光化学有关，可以应用于纳米光刻和未来几代半导体器件技术。电子能谱将用于确定从气相小分子中去除内层电子所需的能量，并研究这些高激发分子失去能量的过程的动力学和能量学。关于分子环境对含碳、氮、氧和氟分子俄歇衰变速率影响的理论和实验研究也将涉及到内壳去激发动力学。
