NMR spectroscopy plays a key role in the characterization of chemical compounds, resulting in an enormous need for sophisticated methods at the Institute of Inorganic and Analytical Chemistry in the Department of Chemistry and Pharmacy at the Westfälische Wilhelms-Universität Münster due its diverse focal points. Current research at the institute in the field of main group element chemistry includes silicon ring compounds and silicon clusters with extraordinary properties. In the field of transition metal chemistry, the research groups deal, amongst others, with N-heterocyclic carbenes, with luminophores and the metal complexes obtained thereof, and with supramolecular aggregates and their applications as functional materials. In the field of bioinorganic chemistry, one focus is the development and characterization of artificial nucleic acids with metal-mediated base pairs. Furthermore, new synthetic methods for the preparation of nucleic acids with a boron-modified backbone are being developed. In collaboration with research groups from the MEET Battery Research Center, the mostly fluorine- and phosphorus-containing electrolytes of battery storage systems and their rearrangement, aging and decomposition products are characterized in detail. Furthermore, the NMR division at the Institute of Inorganic and Analytical Chemistry, which is part of the department-wide NMR center, is one of the general contacts for investigating inorganic and organometallic compounds as well as organic compounds containing phosphorus and fluorine. Without exception, these research areas have a high demand for different NMR methods. High-resolution spectra are required, for example, to determine the structure of complex silicon clusters, to characterize carefully small amounts of substances or compounds of low solubility, to investigate dynamic processes in solution, or for structure determinations. NMR spectroscopy allows a precise structure elucidation even when no crystalline material is available. The requested console will enable the institute to continue to carry out the large number of required measurements at a high level (e.g. NMR measurements accompanying syntheses, complete structure determinations using 1D and homo- or heteronuclear 2D NMR spectroscopy, time-consuming investigations of dynamic behavior). After the modernization, the 400 MHz NMR spectrometer will fulfill excellently the above-mentioned tasks and will reliably enable the application of urgently needed modern NMR methods with a wide measuring range and the measurement of numerous heteronuclei. The procurement is indispensable for the international competitiveness of research at the Department of Chemistry and Pharmacy in Münster and for the competent implementation of current and future projects with third-party funding.

核磁共振波谱在化合物的表征中起着关键作用，导致Westfälische Wilhelms-Universität国立科学技术大学化学和药学系无机和分析化学研究所对复杂方法的巨大需求，因为它具有不同的焦点。该所目前在主族元素化学领域的研究包括具有特殊性质的硅环化合物和硅团簇。在过渡金属化学领域，研究小组主要研究n -杂环碳，发光团及其金属配合物，以及超分子聚集体及其作为功能材料的应用。在生物无机化学领域，一个重点是开发和鉴定具有金属介导碱基对的人工核酸。此外，硼修饰主链核酸的合成方法也在不断发展。与MEET电池研究中心的研究小组合作，详细表征了电池存储系统中主要含氟和含磷的电解质及其重排，老化和分解产物。此外，无机和分析化学研究所的核磁共振部门是研究无机和有机金属化合物以及含磷和氟的有机化合物的一般联系人之一。这些研究领域无一例外地对不同的核磁共振方法有很高的要求。例如，需要高分辨率光谱来确定复杂硅簇的结构，仔细表征少量低溶解度的物质或化合物，研究溶液中的动态过程，或进行结构确定。核磁共振光谱学允许一个精确的结构阐明，即使没有晶体材料可用。所要求的控制台将使该研究所能够继续在高水平上进行大量所需的测量（例如，伴随合成的核磁共振测量，使用1D和同核或异核二维核磁共振波谱进行完整的结构确定，耗时的动态行为调查）。现代化后的400mhz核磁共振谱仪将出色地完成上述任务，并将可靠地实现现代核磁共振测量方法的应用，具有广泛的测量范围和大量的异核测量。采购对于<s:1>国立科学技术大学化学和药学系研究的国际竞争力以及对第三方资助的当前和未来项目的有效实施是必不可少的。
