Acquisition of a Cyber-accessible 400 MHz NMR at the University of Southern Mississippi

在化学研究仪器和设施：多用户计划（CRIF:MU）的支持下，南密西西比大学化学和生物化学系将获得一台网络支持的400 MHz核磁共振（NMR）光谱仪。它将用于各种各样的研究项目，支持结构，反应和分析研究，如1)钒(V)配合物的合成和表征；2)在水介质中开发新的烯烃分解催化剂，加强反应控制和不对称反应；3)非天然氨基酸的合成路线；4)金属氮化富勒烯的表征；5)主客系统作为分子传感器的发展；6)量子化学位移预测方法的实验验证。多核核磁共振波谱是化学中任何分子合成学科中最常用的分析工具。光谱使研究人员能够识别未知物质，并提供关于分子和材料中原子的排列和连通性的信息，即通过检测原子的核自旋特性引起的能级之间的跃迁来提供它们的结构。这个分光仪将加强密西西比南部许多促进本科生和研究生教学的项目。该仪器还将被密西西比州的三所社区学院和该大学位于长滩的墨西哥湾沿岸校区使用。远程访问和操作（网络启用）将是该仪器的一个特点，以提高使用和生产力。

With support from the Chemistry Research Instrumentation and Facilities: Multiuser program (CRIF:MU), the Department of Chemistry and Biochemistry at Southern Mississippi University will acquire a cyber enabled 400 MHz nuclear magnetic resonance (NMR) spectrometer. It will be employed in a wide variety of research projects, supporting structural, reaction, and analytical studies such as 1) synthesis and characterization of vanadium(V) complexes; 2) development of new olefin metathesis catalyst applications in aqueous media, enhanced reaction control and asymmetric reactions; 3) synthetic routes for unnatural amino acids; 4) characterization of metallic nitride fullerenes; 5) development of host-guest systems as molecular sensors; and 6) experimental verification of quantum chemical shift prediction methods.Multinuclear NMR spectroscopy is the most used analytical tool in any molecular-synthetic discipline in chemistry. The spectra enable researchers to identify unknown substances and to provide information on the arrangement and connectivity of atoms in molecules and materials, i.e., their structures by detecting transitions between energy levels arising from the nuclear spin properties of atoms. This spectrometer will enhance many Southern Mississippi programs that promote teaching and learning of undergraduates and graduate students. The instrument will also be used by three community colleges in Mississippi and the University's Gulf Coast campus in Long Beach. Remote access and operation (cyber-enabling) will be a feature of the instrument to enhance usage and productivity.
