This award is supported by the Major Research Instrumentation (MRI) and the Chemistry Research Instrumentation (CRIF) Programs. Professor Timothy Chapp from Allegheny College and colleagues Ivelitza Garcia and Mark Ams have acquired a console upgrade for a 400 MHz nuclear magnetic resonance (NMR) spectrometer. In general, NMR spectroscopy is one of the most powerful tools available to chemists for the structural studies of molecules. It is used to identify unknown substances, to characterize specific arrangements of atoms within molecules, and to study the interactions between molecules in solution or in the solid state. Access to state-of-the-art NMR spectrometers is important to chemists who are carrying out frontier research. The results from these NMR studies have an impact in synthetic organic/inorganic chemistry, materials chemistry, forensics and biochemistry. This instrument is an integral part of teaching as well as research performed by undergraduate students via independent student research and traditional academic coursework. Students work on these projects during independent studies, summer research and senior projects, which prepares them to enter competitive graduate programs and/or industries across the country.This NMR spectrometer enhances research and education at all levels. The instrument is used in studies of molecular torsion and probes the role of fluorine on carbon-hydrogen-pi interactions. It is used in determining Gibbs Free Energies, measuring the potential attractions between substituents in organic molecules. The instrument also serves researchers investigating sulfur chemistries and synthesizing phosphorus-stereogenic frustrated Lewis pairs (FLPs) for catalytic asymmetric hydrogenation. The spectrometer is used to characterize products of synthesis and the protonation of binuclear nickel-phosphido complexes as molecular electrocatalysts for hydrogen production.

该奖项由主要研究仪器 (MRI) 和化学研究仪器 (CRIF) 项目支持。阿勒格尼学院的 Timothy Chapp 教授及其同事 Ivelitza Garcia 和 Mark Ams 已获得 400 MHz 核磁共振 (NMR) 波谱仪的控制台升级。一般来说，核磁共振波谱是化学家研究分子结构最强大的工具之一。它用于识别未知物质，表征分子内原子的特定排列，并研究溶液或固态中分子之间的相互作用。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非常重要。这些核磁共振研究的结果对合成有机/无机化学、材料化学、法医学和生物化学产生影响。该工具是本科生通过独立学生研究和传统学术课程进行的教学和研究的一个组成部分。学生在独立学习、暑期研究和高级项目期间从事这些项目，为他们进入全国各地有竞争力的研究生课程和/或行业做好准备。这款 NMR 波谱仪增强了各个级别的研究和教育。该仪器用于分子扭转研究并探测氟对碳-氢-π 相互作用的作用。 它用于确定吉布斯自由能，测量有机分子中取代基之间的潜在吸引力。 该仪器还为研究硫化学和合成用于催化不对称氢化的磷立体受阻路易斯对 (FLP) 的研究人员提供服务。该光谱仪用于表征作为制氢分子电催化剂的双核镍磷配合物的合成和质子化产物。
