摘要 9413674 驻军 核磁共振光谱学是研究固态材料及其化学的主要工具。核磁共振对原子核的局部电子和磁相互作用的敏感性有助于使其成为阐明未知结构的最有用的诊断工具之一。随着新技术被纳入解决固体化学问题的常规策略,实验所需的设备变得更加复杂。 部分资金用于更新宾夕法尼亚州立大学化学系现有的固态核磁共振光谱仪(Chemagnetics CMX 300光谱仪)。 该仪器配备了双射频辐照通道。各种固态NMR探针可用于核的辐照和固体的高分辨率NMR信号的检测。所要求的升级包括改变计算机硬件和核磁共振操作系统,配备高功率射频放大器的第三个射频通道,用于完成复杂固态核磁共振实验的三个新的核磁共振探针,以及用于离线数据分析、数据存储和自旋动力学计算的快速计算机。 这次光谱仪升级的主要用户将是宾夕法尼亚州立大学的五名研究人员和一组工作集中在固态材料和化学领域的小用户。改进后的仪器将用于以下有代表性的研究:仿生材料的研究;新聚合物材料的合成和表征;新中孔分子筛的表征;柱撑和插层层状固体的研究;沸石中半导体的合成;沸石和相关骨架固体的研究;无定形固体中有序性的研究;玻璃的合成和表征;催化体系的研究;通过高压化学技术合成新的聚合物材料;以及用高分辨率核磁共振光谱研究煤和煤的前体。
英文摘要
Abstract 9413674 Garrison NMR spectroscopy is a major tool in the study of solid-state materials and their chemistry. The sensitivity of NMR to local electronic and magnetic interactions of nuclei has helped to make it one of the most useful diagnostic tools for the elucidation of unknown structures. As new techniques are incorporated into routine strategies to solve chemical problems in solids, the equipment that is necessary for the experiments becomes more sophisticated. Partial funds are provided to upgrade the existing solid-state nuclear magnetic resonance spectrometer (Chemagnetics CMX 300 spectrometer) operating within the Chemistry Department at the Pennsylvania State University. This instrument is equipped with dual radiofrequency irradiation channels. Assorted solid-state NMR probes are available for irradiation of the nuclei and the detection of high-resolution NMR signals of solids. The requested upgrade includes a change in the computer hardware and NMR operating system, a third radiofrequency channel with a high-power radiofrequency amplifier, three new NMR probes for accomplishing sophisticated solid-state NMR experiments, and a fast computer for off-line data analysis, data storage, and calculations of spin dynamics. The major users of this spectrometer upgrade will be five researchers at Penn State and a group of minor users whose work is concentrated in the fields of solid-state materials and chemistry. The improved instrument will be used in the following representative studies: study of biomimetic materials; synthesis and characterization of new polymeric materials; characterization of new mesoporous molecular sieves; studies of pillared and intercalated layered solids; synthesis of semiconductors in zeolites; investigation of zeolites and related framework solids; studies of order in amorphous solids; synthesis and characterization of glasses; studies of catalytic systems; synthesis of new polymeric materials synthes ized by high-pressure chemistry techniques; and study of coal and coal precursors with high-resolution NMR spectroscopy.
