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

该奖项由主要研究仪器、刺激竞争性研究的既定计划（EPSCoR）和化学研究仪器计划提供支持。阿肯色州立大学正在购买一台400兆赫的核磁共振（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教授及其同事Fabricio Medina-Bolivar、Hashim Ali、John Hershberger和Allyn Ontko的研究。该光谱仪可用于多种领域的研究，如开发合成方法以合成具有潜在生物活性的支架和分子，以及研究植物基二苯乙烯类化合物的生物合成途径。总的来说，核磁共振（NMR）波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，以及研究溶液或固体状态下分子之间相互作用的动力学。获得最先进的核磁共振光谱仪是必不可少的化学家谁正在进行前沿研究。本仪器是本科化学专业学生教学、科研和科研训练的重要组成部分。来自当地高中的学生和参加校园研究项目的学生也受益于使用这种最先进的设备。核磁共振光谱仪的奖励旨在加强各级的研究和教育。它尤其影响了促进中小分子结构阐明的方法的发展。该仪器还用于研究持久性新兴有机污染物和聚合物沥青粘合剂。该奖项反映了美国国家科学基金会的法定使命，并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.
