Acquisition of a Departmental Solid State Nuclear Magnetic Resonance Spectrometer for Organic Geochemistry, Experimental Petrology, and Mineral Physics

9724317科迪这笔赠款通过重大研究仪器计划提供225,828美元，作为购买固态核磁共振光谱仪的部分费用，以表征有机地球化学、实验岩石学和矿物物理研究中的化学结构。这种核磁共振波谱仪的使用将是非常多学科的，包括沉积物中成岩反应的大分子产物的有机地球化学表征，火山玻璃中主要元素形态的研究，以及水合硅酸镁中氢的分布研究。许多拟议的研究需要使用固态核磁共振，因为许多样品需要大量光谱分析，因为许多有机和有机-无机化合物的实验室化学分离技术往往非常困难和耗时，或者可能会偏离化合物的原位结构条件。此外，有机地球化学家与具有广泛背景和年龄的岩石学家和矿物物理学家使用最先进的固态核磁共振光谱仪进行合作，为深入了解与地球基本过程直接相关的有机、无机和有机-无机化合物的复杂结构地球化学性质带来了巨大的潜力。***

9724317 Cody This grant, made through the Major Research Instrumentation (MRI) Program, provides $225,828 as partial support of the costs of acquiring a solid state nuclear magnetic resonance (NMR) spectrometer to characterize chemical structures in studies of organic geochemistry, experimental petrology and mineral physics. The use of this NMR spectrometer will be strongly multidisciplinary including organic geochemical characterization of the macromolecular products of diagenetic reactions in sediments, studies of major element speciation in volcanic glasses and studies of the distribution of hydrogen in hydrous magnesium silicates. Many of the proposed studies require the use of solid state NMR as many samples require bulk spectral analysis given that laboratory chemical separation techniques for many organic and organic-inorganic compounds are often very difficult and time consuming or can bias the in situ structural conditions of the compound. Additionally, the collaboration of organic geochemists with petrologists and mineral physicists with widely ranging backgrounds and ages using a state-of-the-art solid state NMR spectrometer brings great potential for new insights into the complex structural geochemistry of organic, inorganic and organic-inorganic compounds that have direct relevance to fundamental Earth processes. ***
