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.

在这个由化学系实验物理化学方案和大气科学系大气化学方案资助的项目中，博尔德的科罗拉多大学的Vaida教授将通过各种物理化学技术进行一项关于水合复合物的研究方案。 待研究的目标物种包括水-氨、水-硫酸、水-硝酸和水-二氧化碳络合物。 这些元素和其他元素在地球大气和气候的化学中起着重要作用。 该项目包括四项具体任务：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）研究其光化学和光化学产物形成; 3）确定随温度变化的平衡常数; 4）通过高分辨率电子和泛频光谱研究这些物种。 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。
