NMR spectroscopy constitutes a key method for the characterization of chemical entities leading to a significant need for various NMR measurements at the Institute for Inorganic and Analytical Chemistry at the WWU Münster where studies in various areas of inorganic chemistry are performed. These include main group compounds including hydrometallation reactions, frustrated Lewis-Pairs (FLPs) including catalytic oligomerization reactions, mixed group-13/group-14 compounds, novel clusters formed from silicon atoms, electron-rich phosphines and their application in the activation of small, unreactive molecules, phosphorous cations with switchable Lewis-acidity, synthesis of particularly voluminous phosphine ligands, compounds with phosphorous-carbon multiple bonds and novel polymeric electrolytes. The transition metal chemistry focusses on the preparation of novel N-heterocyclic carbenes, their metal complexes and metallosupramolecular assemblies from poly-NHCs, catalytic applications for NHC complexes and functional materials for photophysical and photobiological applications. The bioinorganic chemistry focusses on metal-mediated base-pairs derived from model compounds and artificial nucleic acids. All of these research areas feature a strong need for various NMR measurements. High resolution NMR spectra are, for example, are needed for the determination of the complex structures of silicon clusters, for the characterization of small amounts of substances or for substances with low solubility. High resolution NMR spectra are also needed for the characterization of dynamic processes in solution where a comparison of the NMR data with the solid state structures (obtained by X-ray diffraction) and quantum-chemical calculations provides important information. NMR spectroscopy allows a precise structure determination even in cases, where no solid state structure can be determined. The console applied for will enable the continuation of a high level NMR service (about 28.000 measurement annually over the last 5 years) including various complete structure determinations. The upgrade applied for the 400 MHz spectrometer meets the specific demands exceptionally well and will enable modern NMR measurements on a broad basis including spectra on various heteronuclei. The acquisition of the console is of essential to maintain the international competitiveness of research at the University Münster and for the competent execution of our current and prospective internally and externally funded research projects.
