The CNMS offers a Bruker Neo high field, 500 MHz, Nuclear Magnetic Resonance (NMR) spectrometer to characterize the specialty monomers and polymers are synthesized at the CNMS, and the complex molecules and mixtures provided by our users (e.g., lignin compositions). NMR is also used to examine phenomena such as reaction progress and kinetics; reaction mechanism elucidation (including the use of stable isotope labelling); and to identify unknown species in reaction mixtures. We currently have liquids capability only (no solid state).
Applications
One common application is determining the level of deuteration at each carbon atom in a molecule, using 13C NMR. For example, 13C NMR can be used to compare the alkyl region of two deuterated e-caprolactones such as (2-oxepanones): 2-Oxepanone-3,3,4,4,5,5,6,6,7,7-d10 and 2-Oxepanone-3,3,7,7-d4 .
Specifications
- 5-mm liquid double resonance probes (X1 = 1H/19F; X2 tunable 31P to 15N)
- Variable temperature (-80 ºC to +70 ºC)
- Wide variety of 2D NMR pulse programs available
