中文摘要
杰克逊教授的小组得到了实验物理化学项目的支持,对小多原子分子中的紫外多光子解离过程进行了多方面的研究。这项工作试图描述在这种复杂的激光诱导化学环境中发生的一些潜在的基本过程。所研究的分子,如乙炔、烯和甲基乙炔,在紫外光解之前在脉冲分子束中膨胀。产品片段正在通过各种技术进行分析。量子态分布由激光诱导荧光和时间分辨红外发射测量确定。通过共振双光子泵送到光解区里德堡能级来检测氢原子碎片的角和能量分布,然后在远电离区进行时间分辨检测。小的双原子碎片也可以用这些飞行时间技术来检查。
英文摘要
Professor Jackson's group is supported by the Experimental Physical Chemistry Program in a multifaceted investigation of ultraviolet multiphoton dissociation processes in small polyatomic molecules. This work is attempting to characterize some of the underlying basic processes that occur in such complex laser-induced chemical environments. The molecules being investigated, such as acetylene, allene, and methylacetylene, are being expanded in a pulsed molecular beam prior to ultraviolet photodissociation. Product fragments are being analyzed by various techniques. Quantum state distributions are determined by laser induced fluorescence and time-resolved infrared emission measurements. The angular and energy distributions of hydrogen atom fragments are being detected via resonant two-photon pumping to Rydberg levels in the photodissociation zone, followed by time-resolved detection at a distant ionization zone. Small diatomic fragments can also be examined with these time-of-flight techniques.
