Acquisition of a 500 MHz Solid State NMR Spectrometer

该合同将允许购买一台新的500 MHz核磁共振光谱仪，以补充加州大学戴维斯分校Keck固态核磁共振设施现有的光谱仪。这个新仪器是一个宽口径500兆赫光谱仪，具有最先进的多共振，固体样品的多维研究所需的所有功能。新的光谱仪将用于化学、材料科学和地球科学的研究，尽管这项提议的主要研究者（pi）是有直接研究需求的地球科学家。pi整合了研究，检查了矿物从溶液中生长的最早阶段和对反应速率的控制。pi研究小组严重依赖核磁共振光谱，因为它提供了x射线非晶材料的原位结构和动力学信息，包括大范围时间尺度上化学交换速率的信息。加州大学支持购买这台新的光谱仪，因为它也是地球与环境科学跨学科研究和教师招聘的校园倡议的关键。环境材料通常是结晶性差的氧化物或生物分子，其中核磁共振波谱通常是确定结构的唯一合适方法。

0213546CaseyThis award will permit the purchase of a new 500 MHz NMR spectrometer to complement the existing spectrometer in the Keck Solid-State NMR Facility at the University of California at Davis. This new instrument is a wide-bore 500 MHz spectrometer with all of the features necessary for state-of-the-art multi-resonance, multi-dimensional studies of solid samples. The new spectrometer will be used for studies in Chemistry, Materials Science and Earth Science, although the principal investigators (PIs) of this proposal are earth scientists with immediate research needs. The PIs have integrated research that examines the earliest stages of mineral growth from solution and the controls on reaction rates. The PIs research groups rely heavily on NMR spectroscopy because it provides structural and kinetic information on X-ray amorphous materials in situ, including information about rates of chemical exchange over a large range in timescales. Purchase of this new spectrometer is supported by the University of California because it is also key to campus initiatives for growth of interdisciplinary research and faculty recruitment in the Earth and Environmental Sciences. Environmental materials are commonly poorly crystalline oxides or biomolecules where NMR spectroscopy is often the only suitable method for determining structure.
