中文摘要
将进行涉及星团的大气相关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。由于可以研究中性和离子反应,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冰晶上的水发生的平流层相关反应,其确切机制仍在争论中。其他实验将包括簇上的光化学反应、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相关的反应的研究。该项目得到大气化学项目和实验物理化学项目联合资助。
英文摘要
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.
