MRI: Acquisition of a 400 MHz Nuclear Magnetic Resonance Spectrometer to Support Research, Research Training, and Education at Southern Oregon University

该奖项由重大研究仪器项目和化学研究仪器项目联合资助。南俄勒冈大学正在购买一台带有宽带探头的 400 MHz 核磁共振 (NMR) 波谱仪，以支持 Hala Schepmann 教授及其同事 Samuel David 和 Anna F. Oliveri 的研究。该仪器促进了铝化学、有机化学和天然产物领域的研究。 一般来说，核磁共振 (NMR) 光谱是化学家阐明分子结构的最强大工具之一。它用于识别未知物质，表征分子内原子的特定排列，并研究溶液或固态分子之间相互作用的动力学。对于进行前沿研究的化学家来说，使用最先进的核磁共振波谱仪至关重要。该工具增强了系内各级学生的教育、研究和教学工作。来自弱势群体的学生可以利用该仪器进行实践研究和研究培训经验。400 MHz NMR 波谱仪的获奖旨在加强各级的研究和教育，特别是在多原子纳米团簇、有机合成和天然产物等领域。该仪器使研究能够集中于纳米级羟基氧化铝簇的表征，以阐明水溶液中铝的形态，并开发新的合成方法来生产取代苯酚和苯醌环系统。 其他研究包括天然产物氟洛里林和阿斯佩尼格林的全合成，以及 P. elata（非洲柚木）中植物生长激素的鉴定。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。

This award is jointly supported by the Major Research Instrumentation and the Chemistry Research Instrumentation Programs. Southern Oregon University is acquiring a 400 MHz nuclear magnetic resonance (NMR) spectrometer with a broadband probe to support the research of Professor Hala Schepmann and colleagues Samuel David and Anna F. Oliveri. This instrument facilitates research in the areas of aluminum chemistry, organic chemistry, and natural products. In general, Nuclear Magnetic Resonance (NMR) spectroscopy is one of the most powerful tools available to chemists for the elucidation of the structure of molecules. It is used to identify unknown substances, to characterize specific arrangements of atoms within molecules, and to study the dynamics of interactions between molecules in solution or in the solid state. Access to state-of-the-art NMR spectrometers is essential to chemists who are carrying out frontier research. This instrument enhances the educational, research, and teaching efforts of students at all levels in the department. The instrument is leveraged by students from underrepresented groups in hands-on research and research training experiences.The award of the 400 MHz NMR spectrometer is aimed at enhancing research and education at all levels, especially in areas such as polyatomic nanoclusters, organic synthesis, and natural products. This instrument enables research focused on the characterization of nanoscale aluminum oxyhydroxide clusters to elucidate speciation of aluminum in aqueous solution and the development of new synthetic methodologies to produce substituted phenol and benzoquinone ring systems. Other investigations include the total synthesis of the natural products floricolin and aspernigrin and the identification of a plant growth hormone in P. elata (African teak).This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
