The NMR facility maintains the NMR spectrometers of the FMP and supports researchers from inside and outside the FMP in using state-of-the-art NMR spectroscopy, either solid state or solution state and either in collaborations or by providing a walk-on service for routine NMR spectroscopy.


NMR

Nuclear Magnetic Resonance Spectroscopy (NMR): The NMR facility maintains FMP’s NMR spectrometers, enabling internal and external researchers to use both solid-state and solution-state NMR spectroscopy.
NMR spectroscopy allows us to study the electronic environment of individual atoms and their interactions with neighboring atoms, for example to determine the structure and dynamics of molecules. Our facility provides the research groups with two open-access spectrometers (300 MHz and 600 MHz) for their own use. For more complex problems, we collaborate with the scientists using our NMR instruments equipped with cryoprobes. A probe suitable for 31P-NMR spectroscopy is of particular importance because the phosphorylation of different molecules is studied intensively in the Chemical Biology departments.
The solid-state spectrometers are primarily used by the Structural Biology departments to determine the structures of membrane proteins or larger aggregates. For this purpose, a wide range of field strengths and probes with different sample diameters is used. DNP (dynamic nuclear polarization) experiments can also be performed on two spectrometers. Furthermore, the facility receives requests from groups outside of the FMP, as well as from commercial companies located close to the institute. These requests are met in the form of collaborative activities or as a NMR service provided by the facility. The NMR facility also participates in the German DFG-funded G-NMR network of facilities, the iNEXT initiative, and worldwide NMR studies such as the Fab-NMR study by NIST.
