Improved NMR Equipment for Studies of Silicate Glasses and Crystals

小行星9616468 这笔赠款提供了31 100美元，用于部分支持地质和环境科学部的核磁共振光谱仪升级费用，该光谱仪最初于1987年购买，配备了一个超高速、高脉冲、功率魔角旋转（MAS）探头，具有低27-Al背景信号，一个MAS转速控制器和一个MAS转子同步系统。 这些升级将使斯坦福大学的研究人员能够继续使用原位高温NMR光谱法对硅酸盐玻璃和无机固体的结构和动力学进行尖端研究。PI被公认为分子无机地球化学领域的国际领先研究人员之一，使用NMR光谱作为主要工具来阐明矿物和玻璃的原子水平结构。 核磁共振波谱学的最新发展，即多量子魔角自旋（MQMAS）和卫星跃迁（SATRAS）MAS核磁共振，现在将有可能在斯坦福大学与这些升级，并将允许前所未有的表征四极核在更广泛的无机固体。 ***

9616468 Stebbins This grant provides $31,100 as partial support of the costs of upgrading the Department of Geological and Environmental Sciences' nuclear magnetic resonance (NMR) spectrometer, originally purchased in 1987, with a super high speed, high pulse, power magic-angle spinning (MAS) probe with a low 27-Al background signal, an MAS spin rate controller and an MAS rotor synchronization system. These upgrades will allow researchers at Stanford to continue their cutting edge research on the structure and dynamics of silicate glasses and inorganic solids using in situ, high temperature NMR spectroscopy. The PI is recognized as one of the leading international researchers in the field of molecular inorganic geochemistry using NMR spectroscopy as a primary tool to elucidate the atomic level structure of minerals and glasses. Recent developments in NMR spectroscopy, namely, multiple-quantum magic-angle- spinning (MQMAS) and satellite transition (SATRAS) MAS NMR will now be possible at Stanford with these upgrades and will allow unprecedented characterization of quadrupolar nuclei in a much wider range of inorganic solids. ***
