Contributions to Elucidating Heterogeneous Chemistry Involving Ice Crystals and Aqueous Aerosols

将进行与大气有关的涉及团簇的化学反应的实验室实验。这些簇模拟液体或固体气溶胶（冰晶）中/上的条件。由于中性和离子反应都可以研究，因此将研究酸催化或离子机制的作用。一个例子是硝酸氯与水在冰晶上的平流层相关反应，其确切机制仍在争论中。其他实验将包括研究团簇上的光化学反应、团簇上小有机化合物的单分子解离、氨溶剂化以及与海盐颗粒有关的反应。该项目由大气化学计划和实验物理化学计划共同支持。

Laboratory experiments on atmospherically relevant chemical reactions involving clusters will be performed. These clusters mimic conditions in/on liquid or solid aerosols (ice crystals). Since both neutral and ionic reactions can be studied, the role of acid catalyzed or ionic mechanisms will be studied. An example is the stratospherically relevant reaction of chlorine nitrate with water on ice crystals, the exact mechanism of which is still under debate. Other experiments will include studies of photochemical reactions on clusters, the unimolecular dissociation of small organic compounds on clusters, ammonia solvation, and reactions relevant to sea salt particles. This project is supported jointly by the Atmospheric Chemistry Program and the Experimental Physical Chemistry Program.
