Ressources and expertises

UCEIV labs has a very diverse analytical platform combining organic and inorganic matrices characterization techniques.


Nuclear Magnetic Resonance (NMR) :


Avance III NMR spectrometer type NanoBay coupled with Topspin 3.1 software: the value of the magnetic field of the superconducting coil is equivalent to 9.4 T, a 400 MHz proton resonance frequency. It is provided with a BBFO More SmartProbe measuring probe allowing as much as mirrored the direct detection for a wide range of cores (1H, 2D, 13C, 15N, 19F, 31P, …) in liquids. The main application areas are:

  • Qualitative and quantitative determination of the chemical structures of organic compounds in the liquid state, in 1D and 2D.
  • chemical synthesis control, purities, followed by chemical reactions.
  • Study of the molecular dynamics (T1 relaxation time, diffusion coefficient D) and supramolecular interactions.

Electron Paramagnetic Resonance (EPR) :


Bruker EMX EPR spectrometer type with double cavity functions either frequency ~ 9.5 GHz (X band), or frequency of 32GHz ~ (Q band). The magnetic field is modulated to the 100 kHz frequency. The spectra can be recorded at room temperature (25 ° C), liquid nitrogen (-196 ° C), liquid helium (-269 ° C) and the variable temperature of -196 ° C to 300 ° C. The Bruker‘s SYMFONIA and WINERP softwares are used for simulation of EPR spectra and for estimating the concentration of the paramagnetic species (organic and inorganic radicals, coordination complexes, transition metals and rare earths, metallic conductors conduction electrons, defects radiation and defects in semiconductors, marking technique and trapping).
