MRI: Acquisition of a 400 MHz Nuclear Magnetic Resonance (NMR) for Research at Arkansas State University

该奖项得到了主要研究仪器，刺激竞争性研究的既定计划（EPSCoR）和化学研究仪器计划的支持。 阿肯色州州立大学正在购买一台400 MHz核磁共振（NMR）光谱仪，该光谱仪能够进行常规分析和更复杂的实验，以帮助阐明化合物的分子结构。该仪器支持M. Abrar Alam和同事Fabricio Medina-Bolivar，Hashim Ali，John Hershberger和Allyn Ontko。 光谱仪允许在各种领域进行研究，例如开发合成方法以合成具有潜在生物活性的支架和分子，以及研究植物基芪类化合物的生物合成途径。 一般来说，核磁共振（NMR）光谱是化学家用来阐明分子结构的最有力的工具之一。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。对于从事前沿研究的化学家来说，使用最先进的NMR光谱仪是必不可少的。该仪器是化学专业本科生教学、科研和科研训练不可或缺的一部分。 来自当地高中的学生和参加校园研究项目的学生也从使用这种最先进的设备中受益。NMR光谱仪的获奖旨在加强各级的研究和教育。 它特别影响了方法学的发展，以促进中小分子的结构解析。 该仪器还用于研究持续出现的有机污染物和聚合物沥青粘合剂。该奖项反映了NSF的法定使命，并且通过使用基金会的知识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 supported by the Major Research Instrumentation, the Established Program to Stimulate Competitive Research (EPSCoR) and Chemical Research Instrumentation programs. Arkansas State University is acquiring a 400 MHz nuclear magnetic resonance (NMR) spectrometer that has the capabilities to perform both routine analysis and more complex experiments to help elucidate molecular structures of chemical compounds. The instrument supports the research of Professor M. Abrar Alam and colleagues Fabricio Medina-Bolivar, Hashim Ali, John Hershberger and Allyn Ontko. The spectrometer allows research in a variety of fields such as developing synthetic methodologies to synthesize scaffolds and molecules having potential biological activity, and studying biosynthetic pathways of plant-based stilbenoids. 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 is an integral part of teaching as well as research and research training of undergraduate students in chemistry. Students from local high schools and student participating in on-campus research programs for underrepresented minorities also benefit from using this state of the art equipment.The award of the NMR spectrometer is aimed at enhancing research and education at all levels. It especially impacts the development of methodologies to facilitate the structure elucidation of small and medium-sized molecules. The instrumentation is also used to study persistent emerging organic contaminants and polymeric asphalt binders.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.
