Electron Spectroscopic and Theoretical Investigations of Small Molecules

在化学部物理化学计划的这个项目中，将进行电子光谱研究，目的是了解化学对激发分子络合物行为的影响。除了其固有的科学价值外，这项研究还与位置选择X射线光化学有关，并可能在纳米光刻和未来几代半导体器件技术中得到应用。电子光谱学将被用来确定从气相中的小分子中移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。此外，还将对含有碳、氮、氧和氟的分子中分子环境对俄歇衰变速率的影响进行理论和实验研究。

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.
