Thermochemical and Kinetics Studies of Important Radicals and the Thermochemistry of Aqueous Solutions and Solid Salts

这项化学动力学方面的研究是作为物理化学实验计划的一部分得到支持的。这对于理解发生在简单气相化学反应中的基本过程是很重要的。采用一种独特的极低压反应器，研究了氢原子加成到烯丙基的化学动力学，包括基本过程速率常数。这些反应将产生自由基，如乙基、异丙基、叔丁基、HO2、RO2、苯基等。这些物质的歧化及其与卤素和氢原子的反应将被研究。这项研究的输出将是这些自由基的基本化学动力学数据和生成焓，以及化学键和反应性的基本信息。

This research, in chemical kinetics, is supported as part of the Physical Chemistry Experimental Program. It is important for the understanding of the basic processes that take place in simple gas phase chemical reactions. A unique very low pressure reactor has been implemented to study the chemical kinetics, including elementary processes rate constants, of reactions involving hydrogen atom addition to allylic species. These reactions will be used to generate radicals such as the ethyl, isopropyl, tertiary butyl, HO2, RO2, phenyl, etc. Disproportionation of these species and their reactions with halogen and hydrogen atoms will be studied. Outputs of this research will be elementary chemical kinetic data and enthalpies of formation of these radicals as well as basic information on chemical bonding and reactivity.
