0129286ThiemensThis two-year award for a dissertation enhancement program in atmospheric chemistry is part of a US-France collaboration between the University of California, San Diego, and research group at the University Joseph Fourier in Grenoble, France. Greg Michalski, a graduate student of Mark H. Thiemens, will carry out spectroscopic studies under the supervision of Remy Jost at the Physical Spectrometry Laboratory in Grenoble. The objectives of the collaboration are investigations of mass independent fractionation (MIF) mechanisms using spectroscopic analysis of NO2 isotopomers. The collaboration requires the synthesis of symmetric and asymmetric isotopomers of NO2. Mr. Michalski will carry out the spectroscopy on the isotopomers substituting the central nitrogen atom with isotopes with integer and half-nuclear spins. Probing states below the dissociation threshold will be done using Cavity Ringdown Spectroscopy. Mr. Michalski will also be trained to operate the French laser systems and the expansion jet using standard NO2. The US team brings to this collaboration expertise in isotopomer synthesis. This is complemented by French expertise in spectroscopic measurements. The resulting data will provide a basis for a complete and quantitative theory to explain MIF in planetary atmospheres, the geologic record and in meteorites. The collaboration contributes as well to research and education infrastructure. The graduate student will benefit through advanced training on specialized equipment in France and participation in an international team effort. This award represents the US side of parallel proposals to the NSF and the CNRS. NSF will cover travel funds and living expenses for the US graduate student. The CNRS will support visits by French researchers and students to the United States.

Thiemens）的研究生格雷格·米歇尔斯基（Greg Michalski）将在格勒诺布尔（Grenoble）物理光谱实验室的雷米·乔斯特（Remy Jost）的监督下进行光谱研究。 该协作的目标是使用NO2同位素分析的光谱分析研究质量独立分馏（MIF）机制。 该协作需要NO2的对称和不对称同位素的合成。 Michalski先生将对同位素的同位素进行光谱，将中央氮原子用整数和半核自旋代替中央氮原子。 在解离阈值以下的探测状态将使用腔度环光谱法进行。 Michalski先生还将接受使用标准NO2操作法国激光系统和扩展喷气机的培训。美国团队带来了同位素合成方面的合作专业知识。法国专业知识在光谱测量中得到了补充。所得数据将为完整和定量的理论提供基础，以在行星大气，地质记录和陨石中解释MIF。该合作也为研究和教育基础设施做出了贡献。 研究生将通过对法国的专业设备进行高级培训并参加国际团队的努力而受益。该奖项代表了NSF和CNR的平行建议的美国。 NSF将为美国研究生提供旅行资金和生活费用。 CNR将支持法国研究人员和学生前往美国的访问。
