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. ***

9601864 AngerHofer将在佛罗里达大学建立最先进的电子顺磁共振设施。该设施将支持该大学多个系和大学的17名教职员工的研究。研究的一个统一主题是了解各种感兴趣材料中顺磁状态的结构和动态的共同目标。提出的主要仪器包括对现有的EPR（电子顺磁共振）光谱仪的升级，脉冲内旋（电子 - 核双共振）功能的获取以及开发商业上可用的ODMR / ODENDOR（对于磁性旋转型磁性旋转 /可检测到的电子启发量），以及光射频率的频谱频谱），以及频谱）非常低温的EPR应用。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分离的分子（化学），稀土掺杂的半导体（材料科学和工程），低维铁磁铁（物理）以及生物学大分子（药理学和治疗）。共有二十四名学生和博士后同伴（38％的女性参与者）将参与培训和使用这些乐器。教育活动将通过涉及实验室工作的特殊主题以及有关涉及各种大学的学生的理论背景进行正式化。 该设施将通过在电子顺磁共振领域创建卓越中心，对东南地区的研究基础设施产生重大影响。它将补充Tallahassee国家高磁场实验室（NHMFL）可用的仪器，并作为在NHMFL进行的高场和高频实验的分期柱。 ***
