Kinetics of Solid State Chain Reactions

在这个项目中的物理化学计划的 犹他州大学化学系教授怀特 将测量固态链式反应的速率， 使用FTIR光谱学在真实的时间中测量温度矩阵。 氯原子-烃链反应涉及乙烯或 甲基环丙烷将通过激光光解引发， 作为温度和相对温度的函数进行监测 试剂浓度。 这些反应是由 固体薄膜的紫外激光光解， 试剂在低温下的气相沉积 （10 - 100 K）。 %%% 凝聚、无序体系中链式反应的动力学研究 环境还处于婴儿期。 进行的实验 在这个程序将导致反应更深入的了解 自由基在环境中的过程， 限制旋转和平移扩散， 各种各样的技术，包括聚合物的合成 先进的复合材料。

In this project in the Physical Chemistry Program of the Chemistry Division, Professor Wight of the University of Utah will measure the rates of solid-state chain reactions in low temperature matrices in real time using FTIR spectroscopy. Chlorine atom-hydrocarbon chain reactions involving ethylene or methylcyclopropane will be initiated by laser photolysis and monitored as a function of temperature and relative concentration of reagents. These reactions are initiated by ultraviolet laser photolysis of thin solid films formed by vapor deposition of the reagents at cryogenic temperatures (10-100 K). %%% Kinetic studies of chain reactions in condensed, disordered environments are in their infancy. The experiments conducted in this program will lead to a deeper understanding of reactive processes of free radicals in environments that severely restrict rotational and translational diffusion and will impact a wide variety of technologies, including synthesis of polymers and advanced composite materials.
