Photoreactivity of Hydrated Complexes Relevant to Atmospheric Chemistry

在这个由化学学部实验物理化学项目和大气科学部大气化学项目资助的项目中，科罗拉多大学博尔德分校的Vaida教授将通过各种物理化学技术对水合配合物进行研究。要研究的目标物质包括水-氨、水-硫酸、水-硝酸和水-二氧化碳配合物。这些物质和其他物质在地球大气和气候的化学成分中起着重要作用。该项目包括四个具体任务：1)确定目标物种的高分辨率红外、可见光和紫外吸收光谱；2)研究它们的光化学和光化学产物形成；3)确定与温度相关的平衡常数；4)利用高分辨率电子光谱和泛音光谱对这些物种进行研究。研究生和本科生将参与这项研究，以及来自其他国家的大量合作者。

In this project, funded by the Experimental Physical Chemistry Program of the Chemistry Division and the Atmospheric Chemistry Program of the Division of Atmospheric Sciences, Professor Vaida of the University of Colorado at Boulder will conduct a research program on hydrated complexes by means of a variety of physical chemistry techniques. The target species to be investigated include the water-ammonia, water-sulfuric acid, water-nitric acid, and water-carbon dioxide complexes. These, and others, play a role in the chemistry of the earth's atmosphere and its climate. The project consists of four specific tasks: 1) to determine high-resolution infrared, visible, and ultraviolet absorption spectra for the target species; 2) to study their photochemistry and photochemical product formation; 3) to determine temperature-dependent equilibrium constants; and 4) to study these species by high-resolution electronic and overtone spectroscopy. Graduate and undergraduate students will participate in this research, as will a significant number of collaborators from other countries.
