Acquisition of a High Field Solid State NMR Spectrometer

在美国国家科学基金会主要研究仪器（MRI）项目和美国国防部的支持下，William and Mary学院的Gina Hoatson和Robert Vold将获得一台高场（18特斯拉）、多核固态核磁共振（NMR）光谱仪。该设备将使研究人员能够进行以下研究：a)铁电和压电材料；B)高性能氮化碳薄膜；C)技术上重要的导电聚合物；d)生物学上重要的氨基酸和环二肽。核磁共振（NMR）波谱是化学家用来阐明分子结构的最有力的工具。它用于识别未知物质，表征分子内原子的特定排列，以及研究溶液中分子之间相互作用的动力学。获得最先进的核磁共振光谱仪对于开展前沿研究至关重要。这些核磁共振研究的结果将对许多领域产生影响，包括与磨损相关的涂层、超声波换能器和电子执行器以及电致变色器件的发展。此外，氨基酸和环二肽的研究很重要，因为这些模型系统可以深入了解蛋白质折叠、分子识别和酶活性等问题。

With support from the Major Research Instrumentation (MRI) Program at NSF, and the Department of Defense, Profs. Gina Hoatson and Robert Vold at the College of William and Mary will acquire a high field (18 tesla), multinuclear solid state nuclear magnetic resonance (NMR) Spectrometer. This equipment will enable researchers to carry out studies on a) ferroelectric and piezoelectric materials; b) high performance carbon nitride films; c) technologically important conducting polymers; and d) biologically important amino acids and cyclic dipeptides. Nuclear Magnetic Resonance (NMR) spectroscopy is the most powerful tool 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 solution. Access to state-of-the-art NMR spectrometers is essential for carrying out frontier research. The results from these NMR studies will have an impact in a number of areas including development of wear-related coatings, ultrasonic transducers and electronic actuators, and electrochromic devices. In addition, amino acids and cyclic dipeptides are important to study because these model systems yield insight into problems of protein folding, molecular recognition and enzyme activity.
