This award in the Experimental Physical Chemistry program supports the collaborative effort between Physics Departments at two undergraduate institutions, Central Washington University and the University of Wisconsin-La Crosse. Both Universities are public, four-year comprehensive institutions and the principal investigators mentor undergraduate students studying physics, engineering, and chemistry. The research component of this program will be to enhance our understanding of atmospheric and interstellar free radicals. A free radical is a substance with an unpaired electron; typically unstable, they are important intermediates in a number of chemical reactions occurring in the Earth's atmosphere and in space. Using a variety of high-resolution experiments, several free radicals such as ND, FeD, and CH3O will be investigated in the far-infrared region of the electromagnetic spectrum (the area between the infrared and microwave regions). To enhance these investigations, continued work on the discovery of far-infrared laser lines will be performed. Once detected, the frequencies of these laser lines will be measured to fractional uncertainties of a few parts in ten million. Other spectroscopic studies investigating "forbidden" transitions in stable symmetric- and asymmetric-top molecules are also planned. This research is performed in collaboration with a number of visiting scholars, including faculty and students at the University of Oxford, England. Since 1999, twenty-three undergraduates and four visiting graduate students have co-authored nineteen publications from this research laboratory. While sustaining a rigorous research program, the principal investigators will focus their educational efforts on mentoring undergraduate students. Students, from their freshmen through senior years, comprise the bulk of the research team. This experience will provide students with a deeper and broader educational experience, exposing them to research early in their academic careers and serving as excellent preparation for future professional endeavors and graduate school. Beyond the laboratory experience, the principal investigators and undergraduates involved in this research will connect with elementary and middle school students and teachers in a variety of outreach programs through the Center for Excellence in Science and Mathematics Education (CESME).

实验物理化学项目的该奖项支持中央华盛顿大学和威斯康星大学拉克罗斯分校这两个本科院校物理系之间的合作努力。 这两所大学都是公立四年制综合性大学，主要研究人员指导学习物理、工程和化学的本科生。 该计划的研究部分将是增强我们对大气和星际自由基的了解。 自由基是一种带有不成对电子的物质；它们通常不稳定，是地球大气层和太空中发生的许多化学反应的重要中间体。 通过各种高分辨率实验，我们将在电磁波谱的远红外区域（红外和微波区域之间的区域）研究多种自由基，例如 ND、FeD 和 CH3O。 为了加强这些研究，将继续开展远红外激光线的发现工作。 一旦检测到，这些激光线的频率将被测量到千万分之几的分数不确定性。 还计划进行其他光谱研究，调查稳定的对称和不对称顶部分子中的“禁止”跃迁。 这项研究是与许多访问学者合作进行的，其中包括英国牛津大学的教师和学生。 自 1999 年以来，该研究实验室已有 23 名本科生和 4 名访问研究生共同撰写了 19 篇出版物。 在维持严格的研究计划的同时，主要研究人员将把他们的教育工作重点放在指导本科生上。 从一年级到高年级的学生构成了研究团队的主体。这种经历将为学生提供更深入、更广泛的教育经历，让他们在学术生涯的早期接触研究，并为未来的职业生涯和研究生院做好良好的准备。 除了实验室经验之外，参与这项研究的主要研究人员和本科生还将通过科学和数学教育卓越中心（CESME）与各种外展项目中的中小学生和教师建立联系。
