该奖项由主要研究仪器(MRI)和化学研究仪器(CRIF)项目支持。Brandeis大学的Klaus Schmidt-Rohr教授和他的同事对具有固态功能的400 MHz核磁共振光谱仪进行了控制台升级。这种光谱仪允许在各种领域进行研究，例如那些加速具有重大经济意义的化学反应的领域，以及对生物相关物种的研究。总的来说，核磁共振波谱是化学家用来阐明分子结构的最强大的工具之一。它被用来识别未知物质，表征分子中原子的特定排列，并研究分子在溶液或固体中的相互作用。对于正在进行前沿研究的化学家来说，获得最先进的核磁共振光谱仪是很重要的。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了影响。该仪器是本科生、研究生和博士后研究员通过独立的学生研究和传统的学术研究和课程工作进行的教学和研究的组成部分。该仪器可供全国范围内的研究人员使用。在当地，请求的仪器与布兰代斯大学和大波士顿地区的感兴趣的用户共享，用于实际操作的核磁共振测量。授予具有固态能力的400兆赫核磁共振控制台的目的是加强各级的研究和教育，特别是在下列领域的研究和教育：(A)确定介孔氧化物载体上保护性富芳烃有机覆盖层的化学结构；(B)量化交联刺激响应或后改性催化活性聚合物中的官能团浓度；(C)研究催化活性金属有机骨架的结构，包括不同连接体的接近程度；(D)表征生物水下粘合剂；以及(E)确定环境中天然有机物质的结构。

This award is supported by the Major Research Instrumentation (MRI) and the Chemistry Research Instrumentation (CRIF) programs. Professor Klaus Schmidt-Rohr from Brandeis University and colleagues have acquired a console upgrade for a 400 MHz NMR spectrometer with solid state capabilities. This spectrometer allows research in a variety of fields such as those that accelerate chemical reactions of significant economic importance, as well as the study of biologically-relevant species. 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 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, graduate students and postdoctoral fellows via independent student research and traditional academic research and coursework. The instrument is available to researchers nationwide. Locally, the requested instrument is shared with interested users at Brandeis University and in the Greater Boston area for hands-on NMR measurements. The award of a 400 MHz NMR console with solid state capabilities is aimed at enhancing research and education at all levels, especially in areas such as: (a) determining the chemical structure of protective aromatic-rich organic overlayers on mesoporous oxide supports, (b) quantifying functional-group concentrations in cross-linked stimuli-responsive or post-modified catalytically active polymers, (c) studying the structure of catalytically active metal organic frameworks, including the proximity of different linkers, (d) characterizing a biological underwater adhesive, and (e) determining the structure of natural organic matter in the environment.
