With this award from the Chemistry Research Instrumentation and Facilities: Departmental Multi-User Instrumentation program (CRIF:MU), Professor Walter E. Rudzinski and colleagues Michael Blanda, Chad J. Booth, Debra Feakes and Jennifer Irvin from the Department of Chemistry and Biochemistry at Texas State University - San Marcos will upgrade a 400 MHz NMR spectrometer. The upgraded console will allow pulsed field gradient experiments and much faster data collection and increased student accessibility. The spectrometer will also have an auto-sampler. The instrument will be used to support research activities such: 1) self-assembly of inherently chiral calix[6]arenes into helical nanotubes; 2) development of high performance polymeric materials; 3) investigation of polyhedral borane anions; and, 4) study of electroactive polymers with improved n-doping stability and the effects of dopant ions on electroactivityNuclear Magnetic Resonance (NMR) spectroscopy is one of the most powerful tools available to chemists for the elucidation of the structure of molecules. It is used to identify unknown substances, to characterize specific arrangements of atoms within molecules, and to study the dynamics of interactions between molecules in solids and in solution. Access to state-of-the-art NMR spectrometers is essential to chemists who are carrying out frontier research. The results from these NMR studies will have a positive impact in synthetic organic/inorganic chemistry and materials chemistry. This instrument will be an integral part of teaching as well as research.

有了化学研究仪器和设施：系多用户仪器计划(CRIF：MU)颁发的这一奖项，来自德克萨斯州立大学圣马科斯分校化学和生物化学系的沃尔特·E·鲁津斯基教授及其同事迈克尔·布兰达、查德·J·布斯、黛布拉·费克斯和詹妮弗·欧文将升级一台400 MHz核磁共振谱仪。升级后的控制台将允许进行脉冲场梯度实验，数据收集速度更快，学生可访问性更高。光谱仪还将有一个自动取样器。该仪器将用于支持以下研究活动：1)将固有手性杯[6]芳烃自组装成螺旋纳米管；2)开发高性能聚合物材料；3)研究多面体硼烷阴离子；以及4)研究n掺杂稳定性得到改善的电活性聚合物以及掺杂离子对电活性的影响核磁共振光谱是化学家可用于阐明分子结构的最强大的工具之一。它被用来识别未知物质，表征分子中原子的特定排列，并研究固体和溶液中分子之间相互作用的动力学。对于正在进行前沿研究的化学家来说，获得最先进的核磁共振光谱仪是必不可少的。这些核磁共振研究的结果将对合成有机/无机化学和材料化学产生积极的影响。该仪器将成为教学和研究不可或缺的一部分。
