Nuclear Magnetic Resonance (NMR)

Contact : Tina Modjinou

The Spectroscopies (SPE) platform has 2 NMR solution spectrometers (300 and 400 MHz) and a 400 MHz solid spectrometer.

These devices allow for the rapid or in-depth analysis of small organic molecules, polymers and even materials

The two solution devices cover the Institute’s specific needs in several areas :

• Rapid analysis of many small molecules or reaction mixtures
• In-depth analysis of small and large molecules 
• Analysis of polymers and oligomers solution in high-temperature (composition, stereochemistry, tacticity, presence and quantification of terminal clusters)
• Characterization of low-stable species at low temperatures
• Characterization of complex structures (associations of molecules, clusters, association of molecules with biological structures or model systems of biological structures)
• Dynamics of polymers in solution (relaxation time, conformational balances…)

400 MHz STANDARD BORE SPECTROMETER

This 400MHz, ultra shield Bruker spectrometer, piloted by an Advance II console and equipped with a 60-position sample smuggler, allows for rapid, non-destructive analysis of solubilisable molecules or macromolecules.

A wide range of probes is available giving access to the analysis and characterization of many cores in routine : ¹H, ⁷Li,¹³C, ¹⁹F, ²³Na, ²⁹Si, ³¹P, ⁵⁵Mn.

List of probes :

• BBFO broadband 5mm ¹H-BB (¹⁹F and ³¹P -> ¹⁵N) 
  automatic probe tunning ATMA 
  Z gradient 
• BBI 5mm ¹H-BB (³¹P -> ¹⁰⁹Ag)

300 MHz STANDARD BORE SPECTROMETER

This 300MHz, ultra shield Bruker spectrometer is piloted by an Advance I console.

List of probes :

• Sélective ¹H-¹³C 5mm 
  Z gradient 
• BBO 10mm ¹H-BB (³¹P -> ¹⁰⁹Ag)

400 MHz WIDE BORE SOLID SPECTROMETER

This 400MHz Bruker ultra-shield spectrometer plus driven by an Advance III console allows the study of the dynamics of high-temperature and low-temperature polymer systems, the characterization of insoluble macromolecules or reticulated systems.

List of probes :

• 4mm DVT ¹H/¹⁹F/X (¹⁵N -> ¹³C)
• 4mm DVT ¹H/X/Y 
• 4mm DVT ³³S -> ³¹P
• 2.5mm DVT ¹H-¹⁹F/X (¹³C -> ³¹P)
• 1.3mm DVT ¹⁵N -> ³¹P
• static 5mm HP ¹H

Finally, the platform has 2 temperature units allowing low temperature analyses:

• BCU05: ambient temperature analysis at 0°C

BCU-Xtreme: from 0 to -60°C
