Liquid-state 400 MHz NMR spectrometer (ULille)
NMR
Description
NMR spectroscopy is a powerful method to probe the atomic-scale structure and dynamics of a wide range of soft matter samples, including polymer materials, nanocomposites, gels, colloids, surfactant self-assemblies, biomacromolecules and liquid crystals. Because NMR gives information on the local atomic scale, it can easily characterize the bonding environment of atoms in soft materials, which often lack long-range positional order. Furthermore, NMR is a sensitive probe of local dynamics at atomic scale over timescales spanning 15 orders of magnitude, from 10-12 s to 102 s. It can thus be used to study motions, including bond vibrations, conformational changes, rotational and translational motions of the molecules.
This spectrometer is equipped with four probes, including two optimized for the detection of protons and two for that of heteronuclei. This spectrometer is also equipped with a probe for tubes with an outer diameter of 10 mm, which is very useful for the acquisition of insensitive NMR experiments at 400 MHz.
