Upgrade and Development of Advanced (Electron Paramagnetic Resonance/Electron-Nuclear Double Resonance/Optically Detected Magnetic Resonance) EPR/ENDOR/ODMR Instrumentation

9601864安格霍费将在佛罗里达大学建立最先进的电子顺磁共振设施。该设施将支持来自该大学几个系和学院的17名教职员工的研究。这项研究的一个统一主题是了解各种感兴趣材料中顺磁态的结构和动力学。拟议的主要仪器包括升级现有的电子顺磁共振(EPR)光谱仪，获得脉冲ENDOR(电子-核双共振)能力，以及开发商业上没有的ODMR/ODENDOR(光学探测磁共振/光学探测电子-核双共振)光谱仪和用于极低温电子顺磁共振应用的便携式氦-3制冷机。该仪器将用于研究各种材料系统，包括光化学反应物和基质隔离分子(化学)、稀土掺杂半导体(材料科学和工程)、低维铁磁体(物理)和生物大分子(药理学和治疗学)。共有24名学生和博士后助理(38%的女性参与者)将参与这些仪器的培训和使用。教育活动将通过一门涉及实验室工作的专题课程以及来自不同院校的学生的理论背景来正规化。该设施将通过在电子顺磁共振领域创建一个卓越的中心，对东南部地区的研究基础设施产生重大影响。它将补充塔拉哈西国家强磁场实验室(NHMFL)现有的仪器，并作为NHMFL正在进行的高场和高频实验的中转站。***

9601864 Angerhofer A state-of-the-art electron paramagnetic resonance facility will be established at the University of Florida. The facility will support the research of seventeen faculty members from several departments and colleges at the University. A unifying theme of the research is the common goal to understand the structure and dynamics of paramagnetic states in the various materials of interest. Major instrumentation proposed includes the upgrade of an existing EPR (electron paramagnetic resonance) spectrometer, acquisition of pulsed ENDOR (electron-nuclear double resonance) capabilities, and development of a commercially-not-available ODMR/ODENDOR (optically-detected magnetic resonance / optically- detected electron-nuclear double resonance) spectrometer and of a portable helium-three refrigerator for very-low-temperature EPR applications. The instrumentation will be used to study a variety of material systems, including photochemical reactants and matrix- isolated molecules (Chemistry), rare-earth-doped semiconductors (Materials Science and Engineering), low-dimensional ferromagnets (Physics), and biological macromolecules (Pharmacology and Therapeutics). A total of twenty-four students and post-doctoral associates (38% female participants) will be involved in training and use of the instruments. The educational activity will be formalized through a special topics course involving laboratory work along with theoretical background for students from the various colleges involved. %%% The facility will have a large impact on the research infrastructure of the Southeastern region by creating a center of excellence in the area of electron paramagnetic resonance. It will complement the instrumentation available at the National High Magnetic Field Laboratory (NHMFL) in Tallahassee, and serve as a staging post for the high field and high frequency experiments being done at the NHMFL. ***
