项目摘要

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. ***

9724317 Cody 这笔拨款通过主要研究仪器 (MRI) 计划提供，提供 225,828 美元，作为购买固态核磁共振 (NMR) 光谱仪的部分费用支持，用于表征有机地球化学、实验岩石学和矿物研究中的化学结构物理。该核磁共振波谱仪的使用将具有很强的多学科性，包括沉积物中成岩反应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分布的研究。许多拟议的研究都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通常非常困难且耗时，或者可能会影响样品的原位结构条件。化合物。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波谱仪进行合作，为有机、无机和有机-无机的复杂结构地球化学的新见解带来了巨大的潜力。与基本地球过程直接相关的化合物。 ***
