AbstractCHE-0416091Sadtchenko/George WashingtonProfessor Sadtchenko and his coworkers in the Department of Chemistry at the George Washington University are examining the thermal and UV photoinduced chemistry of small oxygenates trapped in dynamic water ice thin films. Using a rapid thermal desorption method coupled with time of flight mass spectrometry, the chemistry of this dynamic molecular interfacial system is being examined. Fundamental information from these studies is relevant to many questions of heterogeneous chemistry in the atmosphere and the environment.With the support of the Analytical and Surface Chemistry Program, Professor Sadtchenko and his coworkers at George Washington University are studying the thermal and photochemistry of small organic molecules trapped in water ice thin films. A novel rapid thermal desorption method developed by Professor Sadtchenko is being applied to studies of the reaction kinetics of these systems, which are relevant to atmospheric and environmental chemistry.

乔治华盛顿大学化学系的Sadtchenko教授和他的同事正在研究动态水冰薄膜中捕获的小含氧化合物的热和紫外光诱导化学。 使用快速热解吸附的方法加上飞行时间质谱，这个动态的分子界面系统的化学正在检查。 这些研究的基本信息与大气和环境中多相化学的许多问题有关。在分析和表面化学计划的支持下，乔治华盛顿大学的Sadtchenko教授和他的同事正在研究水冰薄膜中捕获的小有机分子的热化学和光化学。 Sadtchenko教授开发的一种新的快速热解吸方法正用于研究这些系统的反应动力学，这与大气和环境化学有关。
