Photodissociation and Photodetachment: Product Imaging

在这个由化学部实验物理化学计划支持的项目中，康奈尔大学的Paul Houston将应用产物成像技术来更好地理解光解离和光分离过程。 将进行NCO、SO2、苯甲醛和C2 O的光解研究，以了解母体分子或自由基的初始状态如何影响产物状态分布。 从C2-，O2-，苯酚阴离子，多烯阴离子和烯醇阴离子的分离将被研究，以了解角和能量分布如何作为光剥离波长的函数而变化。 这些研究将提高我们对准束缚态和连续态之间耦合的基本认识，有助于更好地理解大气化学和燃烧中重要的自由基和分子。 此外，正在开发的成像技术可能会对各种不相关的领域产生影响，包括例如断层扫描。

In this project supported by the Experimental Physical Chemistry Program of the Chemistry Division, Paul Houston of Cornell University will apply product imaging techniques to understand better both photodissociation and photodetachment processes. Photodissociation studies of NCO, SO2, benzaldehyde, and C2O will be made in order to learn how the initial state of the parent molecule or radical affects the product state distribution. Detachment from C2-, O2-, phenoxide anions, polyenyl anions and enolate anions will be investigated to learn how the angular and energy distributions vary as a function of photodetachment wavelength. These studies will improve our basic understanding of the coupling between quasi-bound and continuum states.The results of these studies will help provide a better understanding of radicals and molecules important in atmospheric chemistry and combustion. In addition, the techniques of imaging being developed may have an impact on a variety of unrelated fields including, for example, tomography.
